mdp3: configure dma source when displaying new frame

During Linux Bootloader to kernel transition, kernel's first call
to overlay_set would reconfigure dma source configurations. This
reconfiguration could happen before vsync but the corresponding
call to overlay_commit would occur after the vsync. This race
condition could cause artifacts to appear on screen. This issue
only occurs on video mode panels.
