Yu-ting Shen cab5dec425 drm/amd/display: limit display clock to 100MHz to avoid FIFO error
[Why]
when changing display clock, SMU need to use power up DFS and use
DENTIST to ramp DFS DID to switch target frequency before switching back

[How]
fixed the minimum display clock to 100MHz, it's W/A the same with PCO.
