[PATCH] em28xx: fix for Dikom DK300 hybrid USB tuner (aka Kworld VS-DVB-T 323UR )

This patch fix the Dikom DK300 hybrid usb card which is recognized as a
Kworld VS-DVB-T 323UR (card=54).

The patch adds digital tv and solves analogue tv audio bad quality issue.
Moreover it removes the composite and s-video analogue inputs which are 
not present on the board.

Not tested: remote controller
To be done: I attach the usbsnoop obtained some month ago using windows xp.
It seems that with the proposed patch the digital demodulator remains 
activated if the tuner is switched from digital to analogue mode.
Workaorund is to unplug and replug the device when switching from 
digital to analogue.
If someone can explain how to verify the gpio settings using the 
usbsnoop, the above issue perhaps can be resolved.
