drm/i915/display/debugfs: New entry "DRRS capable" to i915_drrs_status
If the connected panel supports both DRRS & PSR, driver gives preference
to PSR ("DRRS enabled: no"). Even though the hardware supports DRRS,
IGT treats ("DRRS enabled: yes") as not capable.
Introduce a new entry "DRRS capable" to debugfs i915_drrs_status, so
that IGT will read the DRRS capability as "DRRS capable: yes".
