Create multiplanar kernel module parameter to define if the driver is
running in single planar or in multiplanar mode. Define the device
capabilities according to the multiplanar kernel parameter. A device can't
support both CAP_VIDEO_CAPTURE and CAP_VIDEO_CAPTURE_MPLANAR at the
same time.

Changes in v5: none
Change in v4:
- Split commit with "Add handler for multiplanar fmt ioctls"
Change in v3:
- Squash commit with "Add handler for multiplanar fmt ioctls"
- Remove functions that only did the `IS_MULTIPLANAR(vcap)` check
- Assign ioctls according to device capabilities
Changes in v2:
- Squash commits to create multiplanar module parameter and to define
the device capabilities
- Move the creation of the multiplanar parameter to the end of
history, so it's only added when all required changes are applied
