drm/amd/display: Refactor and add visual confirm for HW Flip Queue

[Why]
Visual confirm will indicate if driver is programming
the surface address.
Refactor is required because much of the visual confirm
logic is buried deep in the mpcc files.
In addition, visual confirm is not updated during fast updates.

[How]
In order to have visual confirm for driver flips, visual confirm
needs to be updated on every frame, including fast updates.
Add a new hw sequencer interface update_visual_confirm_color,

Previous patch caused crash and had been reverted. This patch

[Why]
1. Driver use umachannelnumber to calculate watermarks for stutter.

dual-channel. The bandwidth should be the same as single-channel.

drm/radeon/dpm: Disable sclk switching on Oland when two 4K 60Hz monitors are connected

Screen flickers rapidly when two 4K 60Hz monitors are in use. This issue
doesn't happen when one monitor is 4K 60Hz (pixelclock 594MHz) and
another one is 4K 30Hz (pixelclock 297MHz).

The issue is gone after setting "power_dpm_force_performance_level" to
"high". Following the indication, we found that the issue occurs when
sclk is too low.

So resolve the issue by disabling sclk switching when there are two
monitors requires high pixelclock (> 297MHz).

v2:
 - Only apply the fix to Oland.

Pull x86 fixes from Borislav Petkov:
 "The three SEV commits are not really urgent material. But we figured
  since getting them in now will avoid a huge amount of conflicts
  between future SEV changes touching tip, the kvm and probably other
  trees, sending them to you now would be best.

  The idea is that the tip, kvm etc branches for 5.14 will all base
  ontop of -rc2 and thus everything will be peachy. What is more, those
  changes are purely mechanical and defines movement so they should be
  fine to go now (famous last words).

  Summary:

   - Enable -Wundef for the compressed kernel build stage

   - Reorganize SEV code to streamline and simplify future development"

drm: simpledrm: fix a potential NULL dereference

The drm_format_info() function returns NULL if the format is
unsupported, but the simplefb_get_validated_format() is expected to
return error pointers.  If we propagate the NULL return then it will
lead to a NULL dereference in the callers.  Swap the NULL and trade it
in for an ERR_PTR(-EINVAL).
