Currently the GGTT offset of a UV plane in a semiplanar YUV FB is tile
size (4kB) aligned. I noticed, that enforcing only this alignment leads
oddly to random memory corruptions on TGL while scanning out Y-tiled
FBs. This issue can be easily reproduced with a UV plane offset that is
not aligned to the plane's tile row size.
Some experiments showed the correct alignment to be tile row size
indeed. This also makes sense, since the de-tiling fence created for the
object - with its own stride and so "left" and "right" edge - applies to
all the planes in the FB, so each tile row of all planes should be tile
row aligned.
In fact BSpec requires this alignment since SKL. On SKL we may enforce
this due to the AUX plane x,y coords check, but on ICL and TGL we don't.
For now enforce this only on TGL; I can follow up with any necessary
change for ICL after more tests.
BSpec requires a stricter alignment for linear UV planes too (kind of a
tile row alignment), but it's unclear whether that's really needed
(couldn't be explained with the de-tiling fence as above) and enforcing
that could break existing user space; so avoid that too for now until
more tests.
v2:
- Clarify the commit log wrt. the address space the alignment applies to.

At least one framebuffer plane on TGL - the UV plane of YUV semiplanar
FBs - requires a non-power-of-2 alignment, so add support for this. This
new alignment restriction applies only to an offset within an FB, so the
GEM buffer itself containing the FB must still be power-of-2 aligned.
Add a check for this (in practice plane 0, since the plane 0 offset must
be 0).

Due to DDB overlaps the pipe enabling sequence is not always crescent.
As the previous patch selects the smallest pipe/transcoder in the MST
stream to be master and it needs to be enabled first, this changes
were needed to guarantee that.
So first lets enable all pipes that do not need a fullmodeset as
those don't have any external dependency and those are the ones that
can overlap with each other.
Then on the second loop it will enable all the pipes that needs a
modeset and don't depends on other pipes like MST master
pipe/transcoder.
Then finally all the pipes that needs a modeset and have dependency
on other pipes, that at this point are alread enabled.
v3: rebased

On TGL the blending of all the streams have moved from DDI to
transcoder, so now every transcoder working over the same MST port must
send its stream to a master transcoder and master will send to DDI
respecting the time slots.
So here adding all the CRTCs that shares the same MST stream if
needed and computing their state again, it will pick the lowest
pipe/transcoder among the ones in the same stream to be master.
Most of the time skl_commit_modeset_enables() enables pipes in a
crescent order but due DDB overlapping it might not happen, this
scenarios will be handled in the next patch.

- Using recently added intel_crtc_state_reset() to set
mst_master_transcoder to invalid transcoder for all non gen12 & MST
code paths
- Setting lowest pipe/transcoder as master, previously it was the
first one but setting a predictable one will help in future MST e
port sync integration
- Moving to intel type as much as we can

- Replaced stdbool.h by linux/types.h

Move all of haswell_crtc_disable() into the encoder
.post_disable() hooks. Now we're left with just
calling the .disable() and .post_disable() hooks
back to back.
I chose to move the code into the .post_disable() hook instead
of the .disable() hook as most of the sequence is currently
implemented in the .post_disable() hook.
We should collapse it all down to just one hook and then the
encoders can drive the modeset sequence fully. But that may
need some further refactoring as we currently call the
ddi .post_disable() hook from mst code and we can't just
replace that with a call to the ddi .disable() hook.
Should also follow up with similar treatment for the enable
sequence but let's start here where it's easier.

HSW+ platforms call encoder .post_disable() and .post_pll_disable()
back to back. And since we don't even disable the PLL in between
let's just move everything into .post_disable().
intel_dp_mst does forward the .post_disable() call to intel_ddi at
the very end of its own .post_disable() hook, so this time MST
I shouldn't even break MST by accident.

We have a few places where we want to reset a crtc state to its
default values. Let's add a helper for that. We'll need the new
__drm_atomic_helper_crtc_state_reset() helper for this to allow
us to just reset the state itself without clobbering the
crtc->state pointer.
And while at it let's zero out the whole thing, except a few
choice member which we'll mark as "invalid". And thanks to this
we can now nuke intel_crtc_init_scalers().

In order to eliminate intel_pipe_to_cpu_transcoder() (and its
crtc->config usage) let's pass the cpu transcoder to
assert_pipe() so we don't have to do the pipe->cpu transcoder
lookup on HSW+.
On VLV/CHV this can get called during eDP init, which
happens before crtc->config->cpu_transcoder is even
populated. So currently we're always reading PIPECONF(A)
there even if we're trying to check the state of some
other pipe.
