[PATCH v8 02/22] drm/i915/dmc: Add pipe dmc registers and bits for DC Balance

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

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add pipe dmc registers and  access bits for DC Balance params
configuration and enablement.

--v2:
- Separate register definitions for transcoder and
pipe dmc. (Ankit)
- Use MMIO pipe macros instead of transcoder ones. (Ankit)
- Remove dev_priv use. (Jani, Nikula)

--v3:
- Add all register address, from capital alphabet to small. (Ankit)
- Add EVT CTL registers.
- Add co-author tag.
- Add event flag for Triggering DC Balance.

--v4:
- Add DCB Flip count and balance reset registers.
