staging: bcm2835: Don't probe if no camera is detected

It is a waste of resources to load the camera driver in case there isn't
a camera actually connected to the Raspberry Pi. This solution also
avoids a NULL ptr dereference of mmal instance on driver unload.

Fixes: 7b3ad5abf027 ("staging: Import the BCM2835 MMAL-based V4L2 camera driver.")
