The RFBI driver currently relies on the omap_dss_device struct to receive the
rfbi specific timings requested by the panel driver. 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.
