OMAPDSS: OVERLAY: Add position and replication as overlay caps
Add position and replication as overlay caps, and pass overlay caps as an argument to the corresponding functions. Adding position and replication to overlay caps seems a bit unnecessary, but it allows us to use the corresponding functions for writeback too. These caps will be set for all overlays, but not for writeback. This is done so writeback can reuse dispc_ovl_setup() to the maximum. Signed-off-by: Archit Taneja <archit@ti.com>
