This patch adds support for the Elgato Video Capture, version 2, device.
The device is added based on the code for
CX231XX_BOARD_HAUPPAUGE_USBLIVE2, it is simply a
copy of the code for that board, with the proper USB device info for the
Elgato Video Capture V2 device.

I have opened the device, and found out that it uses the CX 23112 chip.
There is no visual indication on the device that it is "Version 2", but
the lsusb shows "Video Capture V2".
I do not know how the "Version 1" looks like.
Based on the fact that "lsusb -v" on the following page
http://www.linuxtv.org/wiki/index.php/Hauppauge_USB-Live-2
matches very closely the "lsusb -v" from my device, I decided to patch
the cx231xx driver, using the same setup
as defined in the driver for the CX231XX_BOARD_HAUPPAUGE_USBLIVE2 device.
The patch has been tested using vlc to play and grab some VHS cassettes,
in PAL format.
I get nice video and sound quality. My VHS player does not have stereo,
so I cannot test if it supports stereo.
The Elgato Video Capture, version 1, is already defined in the em2xx driver
em28xx/em28xx.h:#define EM2860_BOARD_ELGATO_VIDEO_CAPTURE 33
with this USB info :
{ USB_DEVICE(0x0fd9, 0x0033),
.driver_info = EM2860_BOARD_ELGATO_VIDEO_CAPTURE},
So my device, the version 2, has different hardware compared to version 1.
Here is the output of "lsusb -v" for my device :
Bus 002 Device 023: ID 0fd9:0037 Elgato Systems GmbH Video Capture v2
