[v6,10/10] drm/i915/psr: Add panel replay sel update support to debugfs interface

Commit Message

Add panel replay selective update support to debugfs status interface. In
case of sink supporting panel replay we will print out:

Sink support: PSR = no, Panel Replay = yes, Panel Replay Selective Update = yes

and PSR mode will look like this if printing out enabled panel replay
selective update:

PSR mode: Panel Replay Selective Update Enabled

Current PSR and panel replay printouts remain same.
