Liu Ying e66866c542 video: ipu_disp: wait for DP SF end irq when disabling sync BG flows 
Instead of waiting for DC triple buffer to be cleared, this patch
changes to wait for a relevant DP sync flow end interrupt to come
when disabling sync BG flows.  In this way, we align the implement
to the freescale internal IPUv3 driver.  After applying this patch,
an uboot hang up issue at the arch_preboot_os() stage, where we
disable a relevant ipu display channel, is not observed any more on
some MX6DL platforms.
