drm/amd/display: Set gamma not working on MPO planes

[Why]
Set gamma not working on certain planes in MPO configuration
Root cause is that video format (YUV-420) isn't allowed for IGAM where
gamma is applied.
Fix is not easy though:
1. allowing will not work because IGAM is before ICSC so RGB gamma would
be applied on YUV pixels.
2. Moving OS gamma to DGAM or RGAM resulted in weird artifacts.

Ultimately the root cause for these artifacts was due to handling end
points and the fact that YUV->RGB conversion will frequently "overshoot"
FP 1.0 value. DCE  has a single end point and slope, so we would take max.
In nightlight mode, blue channel is reduced, sometimes to flat 0 line,
but red is virtually unchanged. Any "overshot" in blue will be clipped
to 1 (max R,G,B) instead of max blue value.

[How]
Fortunately, this can be fixed on DCN where we have end point and slope
for all three color channels. We cannot fix this problem on DCE.

Other things fixed:
- switch (back) to using RGAM for OS gamma instead of IGAM
- add coeffs for 709 YUV->RGB (we used RGB->YUV for both conversions)
- switch color temperature method to scaled bradford - otherwise we would
have clipping problems that caused us to switch to IGAM for OS gamma
in the first place.
- comments and some minor improvements - there are some more issues but
they will be addressed in separate commits.

drm/amdgpu: Add DCC flags for GFX9 amdgpu_bo

[Why]
Hardware support for Delta Color Compression (DCC) decompression is
available in DC for GFX9 but there's no way for userspace to enable
the feature.

Enabling the feature can provide improved GFX performance and
power savings in many situations.

[How]
Extend the GFX9 tiling flags to include DCC parameters. These are
logically grouped together with tiling flags even if they are
technically distinct.

This trivially maintains backwards compatibility with existing
users of amdgpu_gem_metadata. No new IOCTls or data structures are
needed to support DCC.

This patch helps expose DCC attributes to both libdrm and amdgpu_dm.

commit d4e869b6b5d6 ("drm/amdgpu: add ring test for page queue")'

local variable ring is reused and changed, so amdgpu_ttm_set_buffer_funcs_status(adev, true)
is skipped accidently. As a result, amdgpu_fill_buffer() will fail, kernel message:

drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h - part2

[Why]
In DCN we want direct DAL to SMU calls, with as little as possible
interference by pplib. The reason for each pp_smu interface mapping to
1 SMU message is so we can have the sequencing of different SMU message
in dal and shared across different OS. This will also simplify
debugging as DAL owns this interaction and there's no confusion about
division of ownership.

[How]
Part 2: Separate set_min_deep_sleep_dcfclk message from the SMU
messages that are sent as part of dm_pp_apply_clock_for_voltage_request.
