drm/amd/display: Apply 60us prefetch for DCFCLK <= 300Mhz
[Description]
- Previously we wanted to apply extra 60us of prefetch for min DCFCLK
(200Mhz), but DCFCLK can be calculated to be 201Mhz which underflows
also without the extra prefetch
- Instead, apply the the extra 60us prefetch for any DCFCLK freq <=
300Mhz
