Dillon Varone ce902d987a drm/amd/display: Enforce minimum prefetch time for low memclk on DCN32 
[WHY?]
Data return times when using lowest memclk can be <= 60us, which can cause
underflow on high bandwidth displays with a workload.

[HOW?]
Enforce a minimum prefetch time during validation for low memclk modes.
