commit 53af98c091bc ("drm/amdgpu/gfx9: switch to golden tsc registers
for renoir+")

Renoir and newer gfx9 APUs have new TSC register that is
not part of the gfxoff tile, so it can be read without
needing to disable gfx off.

This is necessary for s0i3 to work well on GNOME41 which tries to access
timestamps during suspend process causing GFX to wake up.

Modified to take use ASIC IDs rather than IP version checking
Please apply this to both 5.14.y and 5.15.y.

Please note that 5.14.y is end-of-life as the front page of kernel.org
should show.

Thanks, I didn't realize that until now.
