[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 Reviewed-by: Nevenko Stupar <nevenko.stupar@amd.com> Reviewed-by: Jun Lei <jun.lei@amd.com> Acked-by: Tom Chung <chiahsuan.chung@amd.com> Signed-off-by: Alvin Lee <alvin.lee2@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
