Blackfin: shutdown video DMA when booting Linux
In case there is no frame buffer driver present in Linux to hand over the
PPI LCD DMA upon boot, the DMA initiated by u-boot to display the splash
screen runs unattended. Therefore always stop the video driver in u-boot
before starting Linux. If people don't want this behavior, then they can
simply stub out the video_stop() function in their board video driver.
