drm/amd/display: Fix monitor flash issue

[Why & How]
For a some specific monitors, when connected on boot or hot plug,
monitor flash for 1/2 seconds can happen during first HDCP query
operation. Ading some delay in the init sequence for these monitors
fixes the issue, so it is implemented as monitor specific patch.
