[PATCH 28/43] drm/amd/display: set dram speed for all states

[Alex Deucher]

From: Dillon Varone <dillon.var...@amd.com>

[WHY?]
If higher states have memory speed set to 0 MT/s currently they do not get set
to the highest value which can cause validation failures.

[HOW?]
Set unpopulated higher states to max value.
