drm/amd/powerplay: raven 4k@60hz dp monitor always flicking
[WHY] clock unit mis-match between caller DC and SMU interface.
dc pass lock in mhz. the same unit as smu. no covert is needed.
[HOW] remove covert_10k_to_mhz in smu interface
this fixes corruption issue with 4k @60 display and stutter
mode enable
