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)
