From: Aditya Swarup <aditya.swarup@xxxxxxxxx>
This function sets the VRR property for connector based
on the platform support, EDID monitor range and DP sink
DPCD capability of outputing video without msa
timing information.
v8:
* Use HAS_VRR, remove drm_conn declaration (Jani N)
* Fix typos in Comment (Jani N)
v7:
* Move the helper to separate file (Manasi)
v6:
* Remove unset of prop
v5:
* Fix the vrr prop not being set in kernel (Manasi)
* Unset the prop on connector disconnect (Manasi)
v4:
* Rebase (Mansi)
v3:
* intel_dp_is_vrr_capable can be used for debugfs, make it
non static (Manasi)
v2:
* Just set this in intel_dp_get_modes instead of new hook (Jani)
