[media] Support for Elgato Video Capture 

This patch allows this device successfully to show video, at least from
its composite input.

I have no information about the true hardware contents of this device and so
this patch is based solely on fiddling with things until it worked. The
chip appears to be em2860, and the closest device with equivalent inputs
is the Typhoon DVD Maker. Copying the settings for that device appears
to do the trick. That's what this patch does.

[mchehab@redhat.com: update CARDLIST.em28xx accordingly, via script]
