Introduce a padding round between the DMA line and block modes. Do this based on whether DMA is actually being used, when block mode is first requested. This relieves the driver of doing an UNSET ahead of vsync which could cause blinks in all such transition scenarios. This approach should lead to smooth transitions for multiple targets with the exception of secure videos, where there could be a blink in any of the different approaches we use.
