Added support for Hauppauge NOVA HD DVB-S/S2 USB

To whom it may concern:

I have take the SU3000 USB DVB-S drivers from www.kernel.org, 3.9-rc6 and backported them into RPI kernel 3.6.y.

Plus I made additions to dw2102.c to recognize Hauppage USB DVB-S device with vendor ID 0x2040 and product ID 0xd900 to be a SU3000 / DS3000 device.

Tested and works well.

Cheers
