drm/amd/display: Fix HDCP 1.X 1A-04 failing

[Why]
On some linux based OS, the hotplug->HDCP start takes longer than
4seconds (by ~100ms) This is due to the HDCP delay (3 sec) so we only
have 1 second to hotplug->stream enablement, which is not enough for
certain OS configs.

[How]
Change the Delay to 0 seconds. From testing it seems like 0 Seconds can
pass 1.x and 2.x compliances
