V4L/DVB (4029): [PATCH] Genpix 8PSK->USB driver (Take 2)

This is a patch which includes support for the GENPIX 8PSK->USB module.  The
board supports QPSK, BPSK and 8PSK decoding (though I don't think it will be
DVB-S2 compliant) With the following patch, the boad is equivalent to a budget
card (no CA Module)
The patch which adds 8psk suppot will follow, but is seperate, as it requires
DVB-S2 support
More info on the board can be found at www.genpix-electronics.com (and they
host the requisite firmwares there as well)
