In order to use a common VSC SDP Colorimetry calculating code on PSR,
it adds a compute routine for PSR VSC SDP.
As PSR routine can not use infoframes.vsc of crtc state, it also adds new
writing of DP SDPs (Secondary Data Packet) for PSR.
PSR routine has its own scenario and timings of writing a VSC SDP.
v3: Replace a structure name to drm_dp_vsc_sdp from intel_dp_vsc_sdp
v4: Use struct drm_device logging macros
v10: 1) Fix packing of VSC SDP where Pixel Encoding/Colorimetry Format is
not supported.
2) Change a checking of PSR state.

Compared to implementation of DP and HDMI's encoder->infoframes_enabled,
the lspcon's implementation returns its active state. (we expect enabled
infoframe states of HW.) It leads to pipe state mismatch error
when ddi_get_config is called.
Because the current implementation of lspcon is not ready to support
readout infoframes, we need to return 0 here.
In order to support readout to lspcon, we need to implement read_infoframe
and infoframes_enabled. And set_infoframes also have to set an appropriate
bit on crtc_state->infoframes.enable

Infoframe SDP), it replaces intel_dp_vsc_enable() function and
intel_dp_hdr_metadata_enable() function to intel_dp_set_infoframes()
function.
And it removes unused functions.
Before:
intel_dp_vsc_enable() and intel_dp_hdr_metadata_enable() compute sdp
configs and program sdp registers on enable callback of encoder.
After:
It separates computing of sdp configs and programming of sdp register.
The compute config callback of encoder calls computing sdp configs.
The enable callback of encoder calls programming sdp register.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

All these ROUNDING_FACTORs and whatnot are making this thing hard to
read. Get rid of them. And let's massage some of the fractions to
give us less questionable intermediate results and perhaps less
divisions.
Also looks like a good helping of 64bit math stuff is needed to
avoid some of overflows present in the current code. There
might still be a few overflows, namely when calculating
link_clks_available/samples_room (would require a huge hblank
though), and potentially when calculating hblank_rise (not sure
how large link_clks_active can get).
It looks like we're still not calculating exactly what the spec says
since we truncate tu_data and tu_line early. But I'm too lazy to
figure out if we could avoid that.

Display WA #1105 says that FBC requires PLANE_STRIDE to be a multiple
of 512 bytes on gen9 and glk.
This is definitely true for glk as certain tests (such as
igt/kms_big_fb/linear-16bpp-rotate-0) are now failing when the
display resolution results in a plane stride which is not a
multiple of 512 bytes.
Curiously I was not able to reproduce this on a KBL. First I
suspected that our use of the FBC override stride explain this,
but after trying to use the override stride on glk the test
still failed. I did try both the old CHICKEN_MISC_4 way and
the new FBC_STRIDE way, neither had any effect on the result.
Anyways, we need this at least on glk. But let's trust the spec
and apply the w/a for all gen9 as well, despite being unable to
reproduce the problem.

Let's just calculate the hsync rate on demand. No point in wasting
space storing it and risking the cached value getting out of sync
with reality.

Pass the entire connector state to intel_{gmch,pch}_panel_fitting().
For now we just need to get at .scaling_mode but in the future we'll
want access to the margin properties as well.

Make things a bit more abstract by replacing the pch_pfit.pos/size
raw register values with a drm_rect. Makes it slighly more convenient
to eg. compute the scaling factors.
v2: Use drm_rect_init()

Most of the pfit functions are of the form:
func()
{
if (pfit_enabled) {
...
}
}
Flip the pfit_enabled check around to flatten the functions.
And while we're touching all this let's do the usual
s/pipe_config/crtc_state/ replacement.

Fix skl_update_scaler_crtc() to deal with different scaling
modes correctly. The current implementation assumes
DRM_MODE_SCALE_FULLSCREEN. Fortunately we don't expose any
border properties currently so the code does actually end
up doing the right thing (assigning a scaler for pfit).
The code does need to be fixed before any borders are
exposed.
Also we have redundant calls to skl_update_scaler_crtc() in
dp/hdmi .compute_config() which can be nuked. They were anyway
called before we had even computed the pfit state so were
basically nonsense. The real call we need to keep is in
intel_crtc_atomic_check().
v2: Deal witrh skl_update_scaler_crtc() in intel_dp_ycbcr420_config()

The early check for compressed_bpp being zero is too early, as it is hit
also when DSC is not enabled. Move the checks down to where the values
are actually needed. This is a paranoid check for a situation that
should not happen, so we don't really care about handling it gracefully
apart from not oopsing.

Remove a number of inlines from .c files, and let the compiler decide
what's best. There's more to do, but need to start somewhere, and need
to start setting the example.
