V4L/DVB (8657): cxusb: add lgs8gl5 and support for Magic-Pro DMB-TH usb stick

Add support for Magic-Pro DMB-TH usb stick.  DMB-TH is the HDTV broadcast
standard used in Hong Kong and China.
[...]
I've also attached a second patch against the dvb-apps repository which
adds a DMB-TH scan file for Hong Kong.

Since the ProHDTV stick contains a DMB-TH decoder (lgs8gl5) onboard,
it outputs MPEG-TS to the PC.
