The DSI interface is represented as a platform device, using the DSI platform driver(dsi.c). The current DSI driver design is capable of running only one instance of a DSI device. On OMAP4, there are 2 very similar DSI modules which can be represented as instances of "omapdss_dsi" platform device. Add member "module" in "dssdev.phy.dsi" that tells us which DSI module's lanes the panel is connected to. Modify dsi.c functions to take the device's platform_device struct pointer, provide functions dsi_get_dsidev_from_dssdev() and dsi_get_dsidev_from_id() take the panel's omap_dss_device and module number respectively, and return the platform_device pointer. Currently, the dsi struct is declared globally and is accessed when dsi data is needed. The new pdev argument will be used later to provide the platform device's dsi related data.
