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.

* Copyright (c) 1999-2005 Joerg Heckenbach <joerg@heckenbach-aw.de>
*
* This module is part of usbvision driver project.
*
* Let's call the version 0.... until compression decoding is completely
* implemented.
*
* This driver is written by Jose Ignacio Gijon and Joerg Heckenbach.
* It was based on USB CPiA driver written by Peter Pregler,
* Scott J. Bertin and Johannes Erdfelt
* Ideas are taken from bttv driver by Ralph Metzler, Marcus Metzler &
* Gerd Knorr and zoran 36120/36125 driver by Pauline Middelink
* Updates to driver completed by Dwaine P. Garden
*
* TODO:
* - use submit_urb for all setup packets
* - Fix memory settings for nt1004. It is 4 times as big as the
* nt1003 memory.
* - Add audio on endpoint 3 for nt1004 chip.
* Seems impossible, needs a codec interface. Which one?
* - Clean up the driver.
* - optimization for performance.
* - Add Videotext capability (VBI). Working on it.....
* - Check audio for other devices
