[PATCH 3/7] drm/i915/vrr: Introduce new field for VRR mode

[Ankit Nautiyal]

The VRR timing generator can be used in multiple modes of operation:
dynamic refresh rate (VRR), content-matched refresh rate (CMRR), and
fixed refresh rate (Fixed_RR).

Currently, VRR and CMRR modes are supported, with Fixed_RR mode
forthcoming.

To track the different operational modes of the VRR timing generator,
introduce a new member 'mode' to the VRR struct.
