drm/amd/display: Add debugfs to disallow eDP Replay entry

Browse source

[Why & How]
Test applications need to read CRC from eDP sink side, but sink
replay feature prevents proper CRC reading and causing timeout.

Add disallow_edp_enter_replay debugfs interface to allow test apps
to temporarily disable Replay for CRC operations.
