This makes the RFBI interface driver dependent on the omap_dss_device struct. Make the RFBI driver data maintain it's own rfbi specific timings field. The panel driver is expected to call omapdss_rfbi_set_interface_timings() to configure the rfbi timings before the interface is enabled. The function takes a void pointer rather than a pointer to rfbi_timings struct. This is because this function will finally be an output op shared across different outputs to set custom or private timings.
