Mauro Carvalho Chehab d6a643275a media: em28xx: add support for new of Terratec H6 
There's a new version of Terratec H6 with uses USB ID
0ccd:10b2. This version is similar to the old one (with is
supported via the HTC entry), except that this one has the
eeprom on the second bus.

On this board, one side of this board is labeled with:
	dvbc v2.0
The other side with:
	94V-0, MO2, RK-4221 with huge digits: 1107

With those patches, the board is properly detected:

    em28xx 1-1.5:1.0: New device TERRATEC TERRATCE H5 MKII @ 480 Mbps (0ccd:10b2, interface 0, class 0)
