Merge output work from Archit

The series removes bunch of dssdev references from the omapdss output drivers.
This is made to let us move to a common panel framework later, and also allows
us to implement OMAP's writeback support, which has been proven difficult with
the current output drivers.

OMAPDSS: APPLY: Constify timings argument in dss_mgr_set_timings
OMAPDSS: DPI: Add locking for DPI interface
OMAPDSS: Displays: Add locking in generic DPI panel driver
OMAPDSS: DPI: Maintain our own timings field in driver data
OMAPDSS: DPI displays: Take care of panel timings in the driver itself
OMAPDSS: DSI: Maintain own copy of timings in driver data
OMAPDSS: DSI: Add function to set panel size for command mode panels
OMAPDSS: DSI: Update manager timings on a manual update
OMAPDSS: HDMI: Use our own omap_video_timings field when setting interface timings
OMAPDSS: HDMI: Add locking for hdmi interface set timing functions
OMAPDSS: SDI: Create a function to set timings
OMAPDSS: SDI: Maintain our own timings field in driver data
OMAPDSS: VENC: Split VENC into interface and panel driver
OMAPDSS: VENC: Maintain our own timings field in driver data
OMAPDSS: RFBI: Remove partial update support
OMAPDSS: RFBI: Add function to set panel size
OMAPDSS: DSI: Maintain copy of pixel format in driver data
OMAPDSS: RFBI: Maintain copy of pixel size in driver data
OMAPDSS: RFBI: Maintain copy of number of data lines in driver data
OMAPDSS: DPI: Maintain copy of number of data lines in driver data
OMAPDSS: SDI: Maintain copy of data pairs in driver data
OMAPDSS: DSI: Maintain copy of operation mode in driver data
OMAPDSS: DSI: Rename dsi_videomode_data to dsi_videomode_timings
OMAPDSS: DSI: Maintain copy of video mode timings in driver data
OMAPDSS: RFBI: Maitain copy of rfbi timings in driver data
OMAPDSS: VENC: Maintain copy of venc type in driver data
OMAPDSS: VENC: Maintian copy of video output polarity info in private data
