drm/i915/display/vrr: Configure and enable VRR in modeset enable
This patch computes the VRR parameters from VRR crtc states
and configures them in VRR registers during CRTC enable in
the modeset enable sequence.
v2:
* Remove initialization to 0 (Jani N)
* Use correct pipe %c (Jani N)
v3:
* Remove debug prints (Ville)
* Use cpu_trans instead of pipe for TRANS_VRR regs (Ville)
