drm/amd/display: Defer DIG FIFO disable after VID stream enable
[Why]
On some monitors we see a brief flash of corruption during the
monitor disable sequence caused by FIFO being disabled in the middle
of an active DP stream.
[How]
Wait until DP vid stream is disabled before turning off the FIFO.
The FIFO reset on DP unblank should take care of clearing any FIFO
error, if any.
