linux: mm Add task for V4L2 multiplexed streams
There have been much debate about how multiplexed streams should be
modeled in V4L2. There are multiple touch points in the BSP for this
both for CSI-2 buses and to some extend GMSL.
Add a catch all task that can collect all BSP use-cases where the
current V4L2 limitations are worked around. Then when the upstream
design is prepared we can make sure it will be able to cover all of the
BSP needs.
