drm/amd/display: Add Replay capability and state in debugfs
[Why & How]
User can get the panel replay capability and state for debug.
sudo cat /sys/kernel/debug/dri/0/eDP-1/replay_capability
"Sink support: no" - if panel doesn't support Replay
"Sink support: yes" - if panel supports Replay
"Driver support: no\n" - if driver doesn't support Replay
"Driver support: yes\n" - if driver supports Replay
sudo cat /sys/kernel/debug/dri/0/eDP-1/replay_state
It will return current panel replay state
