drm/amd/display: Waiting for 1 frame to fix the flash issue on PSR1

Browse source

[Why]
Needs more frames waiting before the PSR_Exit sending for the specific
TCON.

[How]
Add relock_delay_frame_cnt to control how many frames waiting are needed
before the PSR_Exit sending. The default value is 0. The Driver side can
set this variable for specific TCONs.
