dispc_mgr_disable_digit_out() needs to wait until the DIGIT output is turned off. This is done with either VSYNC irq on OMAP2/3 and FRAMEDONETV on OMAP4+. It currently uses a rather hacky way to decide what irq to use. This patch changes dispc_mgr_disable_digit_out to use dispc_mgr_get_framedone_irq to find out if there's framedone irq on this SoC, and if not, uses VSYNC.
