Do the following: - Modify dss_get_dsi_clk_source() and dss_select_dsi_clk_source() to take the dsi module number as an argument. - Create debugfs files for dsi2, split the corresponding debugfs functions. - Split packet_sent_handler irqs for dsi1 and dsi2. - Allow DPI to use these new clock sources.
