drm/amd/display: Fix HDCP failing to enable after suspend
[Why]
On resume some displays are not ready for HDCP, so they will fail if we
start the hdcp authentintication too soon.
Add a delay so that the displays can be ready before we start.
NOTE: Previoulsy this delay was set to 3 seconds but it was causing
issues with compliance, 2 seconds should enough for compliance and the
s3 resume case.
[How]
Change the Delay to 2 seconds.
