[Intel-gfx] [RFC V3 2/2] drm/i915/vrr: Set drm crtc vrr_enabled property

[Bhanuprakash Modem]

This function sets the vrr_enabled property for crtc based
on the platform support and the request from userspace.

V2: Check for platform support before updating the prop.
V3: Don't attach vrr_enabled prop, as it is alreay attached.
