From: Sumit Semwal <sumit.semwal@xxxxxx>
Introduce new enum members for LCD2 Channel and corresponding Overlay Manager.
Represent some of the DISPC register defines with channel as a parameter
to differentiate between LCD, DIGIT and LCD2 channels. Replace the existing
reads/writes to these registers in this new way.
