drm/amd/display: program display clock on cache match

Browse source

[Why]
We seem to have an issue where high enough display clock
will not get set properly during S3 resume if we only
call vbios once

[How]
Expand condition of display clock programming to happen
even when cached display clock matches requested display
clock
