On some systems with Navi3x dGPU will attempt to use BACO for runtime
PM but fails to resume properly. This is because on these systems
the root port goes into D3cold which is incompatible with BACO.
This happens because in this case dGPU is connected to a bridge between
root port which causes BOCO detection logic to fail. Fix the intent of
the logic by looking at root port, not the immediate upstream bridge for
_PR3.

DCN 3.1.4 is reported to hang on s2idle entry if graphics activity
is happening during entry. This is because GFXOFF was scheduled as
delayed but RLC gets disabled in s2idle entry sequence which will
hang GFX IP if not already in GFXOFF.
To help this problem, flush any delayed work for GFXOFF early in
s2idle entry sequence to ensure that it's off when RLC is changed.
commit 4b31b92b14 ("drm/amdgpu: complete gfxoff allow signal during
suspend without delay") modified power gating flow so that if called
in s0ix that it ensured that GFXOFF wasn't put in work queue but
instead processed immediately.
This is dead code due to commit 10cb67eb8a ("drm/amdgpu: skip
CG/PG for gfx during S0ix") because GFXOFF will now not be explicitly
called as part of the suspend entry code. Remove that dead code.

Users report a white flickering screen on multiple systems that

will get pinned to both VRAM carve out and system RAM leading to
this.
Until it can be fixed properly, disable S/G when 64GB of memory or
more is detected. This will force pages to be pinned into VRAM.
This should fix white screen flickers but if VRAM pressure is
encountered may lead to black screens. It's a trade-off for now.
