From: Ville Syrjälä <ville.syrjala at 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)
