drm/i915/psr: Add panel replay sel update support to debugfs interface

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.
