staging: vc04_services: rename BM2835 to BCM2835 in headers comments

In the kernel, when referring to the chip BCM2835, it is more suitable
to use BCM2835 to BM2835. To avoid confusion, and to make things more
consistent, rename the headers titles accordingly.

staging: bcm2835: Break MMAL support out from camera

The BCM2835 camera host is currently the only component that uses the
VCHIQ MMAL interface. This will soon change with the upporting of
BCM2835 ISP, which make use of the same interface.

Break VCHIQ MMAL interface support out from camera host directory to
make it possible for the ISP driver to use it as well.

The only modification to the existing mmal code is the introduction of
EXPORT_SYMBOL() for symbols required by bcm2835-camera and the addition
of the module author and licenses.
