    kernel: add support for videobuf-dma
    
    This adds support for videobuf2-dma driver.
    
    This module contains following flavors:
    - Contiguous
    - Scatter/Gather
    
    Drivers using this can enable 1 of the, or both, depending on their needs.
    
    Due to this, a FILES catch-all is required for the videobuf-dma objects
    as depending on requirements, only 1 of them could get generated.
