[PATCH AUTOSEL 5.19 025/105] drm/amd/display: Fix monitor flash issue

[Sasha Levin]

From: Shah Dharati <dharshah@xxxxxxx>

[ Upstream commit b840b64bc8ed3fc46f6d6aa7f97c43862a33bea5 ]

[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.
