From: Aditya Swarup <aditya.swarup at intel.com>
BugLink: https://bugs.launchpad.net/bugs/1855399
Add definitions for registers grouped under Transcoder VRR function
with necessary bitfields.
Bspec: 49268
v2: Use REG_GENMASK, correct tabs/space indentation and move the
definitions near the transcoder section.(Jani)
v3: Remove unnecessary prefix from bit/mask definitions.(Manasi)
v4: Use 'trans' in macro for better readability.(Manasi)
