This patch set mainly consists of minor fixes for the VPE driver. These fixes
ensure the following:
- The VPE module can be inserted and removed successively.
- Make sure that smaller resolutions like qcif work correctly.
- Prevent race condition between firmware loading and an open call to the v4l2
device.
- Prevent the possibility of output m2m queue not having sufficient 'ready'
buffers.
- Some VPDMA data descriptor fields weren't understood correctly before. They
are now used correctly.
The rest of the patches add some minor features like DMA buf support and
cropping/composing.
Reference branch:

Changes in v3:
- improvements in selection API patch.
- querycap fixes for v4l2 compliance.

Changes in v2:
- selection API used instead of older cropping API.
- Typo fix.
