Merge "Apply LCD manager related parameters" from Archit

The LCD interface drivers(DPI, DSI, RFBI, SDI) do some direct DISPC register
writes to configure LCD manager related fields. This series groups these fields
into a single struct, and let's the interface driver apply these parameters.

This allows us to:

- Check the LCD manager related parameters before applying them.
- Remove some omap_dss_device references as APPLY holds the applied parameters.
