OMAPDSS: DSI: simplify dsi configuration
We have a bunch of dsi functions that are used to do the basic configuration for DSI. To simplify things, and to make sure we have all the necessary information, create a single dsi config function, which does the basic configuration. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
