V4L/DVB (9038): Add support for the Gigabyte R8000-HT USB DVB-T adapter.

Thanks to Ilia Penev for the tip-off that this device is much the same as
(identical to?) a Terratec Cinergy HT USB XE, and for the firmware hints:
http://linuxtv.org/pipermail/linux-dvb/2008-August/028108.html

DVB functionality tested OK with xine using the usual dib0700 firmware.

This diff is based on the latest latest linuxtv.org v4l-dvb mercurial
repo.
