[Why and How]
- Add a debug option for allocating extra way for cursor
- Remove usage of cache_cursor_addr since it's not gaurenteed
to be populated
- Include cursor size in MALL calculation if it exceeds the
DCN cursor buffer size (and don't need extra way for cursor)

[Why & How]
ODM seamless transitions require DIV_MODE_AUTO. However,
DIV_MODE_AUTO only works when all the horizontal timing params
are divisible by the ODM combine factor. Therefore, disable the
ODM 2:1 policy when the horizontal timing params are not divisible
by 2.

[why]
When user unplugs mst hubs, the current code will forcefully zero
entire mst payload allocation table structure stored in link before we
deallocate actual payload when disabling stream.
During the first disable stream sequence, we will use current mst
payload allocation table to determine if link should be turned off.
Because we zero out it before we are disabling stream, the payload
allocation table stored in link doesn't represent the actual allocation status,
so we turn off link at the first disable stream without waiting until all
streams' payloads have been deallocated. This avoilates the designed
deallocation sequence and caused system hang in DP2 scenario.
[how]
Remove payload during deallocation and never zero payload allocation structure
without actually deallocating payload.

[why]
Original change 594b237b9a ("drm/amd/display: Add
interface to track PHY state") was implemented by assuming stream's
dpms off is equivalent to PHY power off.
This assumption doesn't hold in following situations:
1. MST multiple stream scenario, where multiple streams are sharing the
same PHY output. Toggle dpms off for one of the stream doesn't power
off the PHY due to the presence of other streams.
2. enable stream failure scenario, where enable stream fails due to
failure of link training. This will cause DPMS off is set to false, while
the actual PHY power state is off in certain cases.
Due to the problematic assumption, the logic will skip disabling
other streams for MST multiple stream scenario, therefore PHY is
not actually powered off.
[how]
1. Rework this refactor by moving PHY state update down to hardware
level, where we update PHY state in place when hardware sequencer
is actually changing the power state of the PHY hardware.
2. Reimplement symclk on TX off workaround in place when we are actually
calling transmitter control to power off PHY in dcn32. Note the workaround is
added due to the lack of proper software interface to set TX while keeping
symclk on. We plan to address this interface problem so we can set TX off
only without affecting symclk in future dcn versions.

[Why]
DC makes use of layer_index (zpos) when picking the HW plane to enable
HW cursor on. However, some compositors will not attach zpos information
to each DRM plane. Consequently, in amdgpu, we default layer_index to 0
and do not update it.
This causes said DC logic to enable HW cursor on all planes of the same
layer_index, which manifests as a double cursor issue if one of the
planes is scaled (and hence scaling the cursor as well).
[How]
Use DRM core helpers to calculate a normalized_zpos value for each
drm_plane_state under each crtc, within the atomic state.
This helper will first consider existing zpos values, and if
identical/unset, fallback to plane ID ordering.
The normalized_zpos is then passed to dc_plane_info during atomic check
for later use by the cursor logic.

420 modes are limited by FMT buffer width of 4096
which requires multi-pipe support in form of ODM
combine. If 420 modes have greater HActive than
4096, the DML logic should accomodate whether
it should be rejected, or ODM combine 2:1 or 4:1

[How]
FMT Buffer limit of 4096 in DCN32. Force ODM
combine depending on HActive and FMT Buffer limit.
Reject modes if TMDS 420 and above 4096.

LLVM 16 (2152 -> 1936), helping clear up the following clang warning:

Additionally, while modifying the arguments to
dml32_CalculateWatermarksMALLUseAndDRAMSpeedChangeSupport(), use 'v'
consistently, instead of 'v' mixed with 'mode_lib->vba'.

[Why & How]
Fix the instatiation sequence for MPC registers and add a few other
missing register definitions that were ommited erroneously when copying
them over to enable runtime initialization of reigster offsets for
DCN32/321

Refactor calculation to remove floating point operations from dmub_srv.
To ensure that 32-bit compilation works well, we use the div64 family of
macros to do integer division for SubVP-related timing parameters.

[why]
Do not need to spend time reprogramming DRR if there were no updates to
the parameters.
[how]
Compare the current stream state to the requested one to determine if an
update is required.
In amdgpu_dm the timing_changed flag is set but never used so can remove it.
Similarly, the stream update for VRR is done after dc_commit and should
not update its adjust field until after the update is completed. The
adjust field is managed by dc_stream_adjust_vmin_vmax and should not be
manually updated in amdgpu_dm.

[Why]
For HDR mode, we get total 512 tf_point and after switching to SDR mode
we actually get 400 tf_point and the rest of points(401~512) still use
dirty value from HDR mode. We should limit the rest of the points to max
value.
[How]
Limit the value when coordinates_x.x > 1, just like what we do in
translate_from_linear_space for other re-gamma build paths.

[Why&How]
Kernel does not have a means to tell the userspace to use software
cursor. Due to lack of this functionality, reducing the max cursor size
is the only way to ensure that power savings of Subview port feature is
utilized for asics that support it. The workaround could be removed
after cursor caching is fixed while a subviewport config is active.
