OMAP: DSS2: Functions to request/release DSI VCs
Introduce functions which request and release VC's. This will be used in panel
drivers in their probes.
omap_dsi_request_vc() takes in the pointer to the omap_dss_device, the VC_ID
parameter which goes into the header of the DSI packets, and returns a Virtual
channel number (or virtual channel register set) which it can use.
omap_dsi_set_vc_id() takes the omap_dss_device pointer, the Virtual Channel
number and the VC_ID that needs to be set for the specifed Virtual Channel.
omap_dsi_release_vc() takes the omap_dss_device pointer and the Virtual Channel
number that needs to be made free.
Initialisation of VC parameters is done in dsi_init().
