If we have more than 4 displays we will run
into dummy irq calls or flip timout issues.

[Why]
Soft hangs occur when FreeSync is engaged since we utilize VUPDATE
(which doesn't fire when holding the pipe lock) to send back vblank
events when FreeSync is active.
[How]
The alternative (working) interrupt source for this mechanism is
VUPDATE_NO_LOCK. We already use this all other DCN revisions so align
dcn30 with those as well.
