[media] cpia2: major overhaul to get it in a working state again

Browse source

This driver was severely broken. This patch makes it work again, and updates
it to the latest V4L2 frameworks (except for videobuf2). It passes the
v4l2-compliance tests and it now handles suspend/resume correctly.

Several custom controls are replaced by new standard controls, only the
USB_ALTERNATE control remains.

Tested with the Hanse HVS-CM500PC USB microscope.
