drm/amd/display: Fix black screen issue on memory clock switch en
[WHY]
With some monitors when multi plane overlay is enabled the memory
clock switching mechanism has to change and, due to an error in the
initialization sequence, it may cause a black screen.
[HOW]
Change the firmware assisted memory clock switch initialization and
tear-down sequence utilizing the prepare_bandwidth and
optimize_bandwidth contexts.
