[media] Add support for dvb usb stick Hauppauge WinTV-soloHD

This patch adds support for the DVB-T/C/T2 usb stick WinTV-soloHD from
Hauppauge. It adds the usb ID 2040:0264 Hauppauge to the cards of the
driver em28xx.

I successfully tested DVB-T/C and the IR remote control with the
firmware dvb-demod-si2168-b40-01.fw.
