[media] cx23885: Add Leadtek Winfast PxPVR2200

Tested:

   TV: http://imgur.com/KNrfsmv
   Firmware used: xc3028-v27.fw

Not tested: audio, component, s-video, mpeg2 encoder, FM radio.

For audio, it uses an CD style cable to connect to the analog "CD_IN" on the motherboard.

I didn't found how to unmute it (alsamixer do not show an CD or AUX channel).
