Jimmy Kizito 2944dbedc7 drm/amd/display: Add work around for AUX failure on wake.
[Why]
When waking from low-power states, a DP sink may remain unresponsive to
AUX transactions.

[How]
Try to toggle DPCD SET_POWER register repeatedly (up to a maximum
timeout value) until DP sink becomes responsive.
