media: usbvision: remove deprecated driver

To quote the TODO of this driver:

--------------------------------------------------------------
The driver is deprecated and scheduled for removal by the end
of 2020.

In order to prevent removal the following actions would have to
be taken:

- clean up the code
- convert to the vb2 framework
- fix the disconnect and free-on-last-user handling (i.e., add
  a release callback for struct v4l2_device and rework the code
  to use that correctly).
--------------------------------------------------------------

Nobody picked this up, so it's time to retire this driver.

There are more than 50 different USB video devices based on
NT1003/1004/1005 USB Bridges. This driver enables using those
devices.
This driver is deprecated and scheduled for removal by the
end of 2020. See the TODO file in drivers/staging/media/usbvision
for a list of actions that have to be done in order to prevent
removal of this driver.
To compile this driver as a module, choose M here: the
module will be called usbvision.
