[PATCH v5 04/17] drm/i915/display: Add VRR DC balance registers

[Mitul Golani <mitulkumar.ajitkumar.golani@intel.com>]

Add VRR register offsets and bits to access DC Balance configuration.

--v2:
- Separate register definitions. (Ankit)
- Remove usage of dev_priv. (Jani, Nikula)

--v3:
- Convert register address offset, from capital to small. (Ankit)
- Move mask bits near to register offsets. (Ankit)
