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