V4L/DVB (5237): Dvb: add new qt1010 tuner module

Browse Source 
gl861: (MSI Megasky)
- hack for enable ZL10353 / QT1010 I2C gate
- use new QT1010 module instead of old code

au6610: (Sigmatek DVB-110)
- hack for enable ZL10353 / QT1010 I2C gate
- use new QT1010 module instead of old code

Tested successfully with au6610 and gl861 devices against fi-Yllas
frequencies. Now it locks perfectly with both devices.
There is a "hack" to enable probable i2c gate in zl10535
demodulator. QT1010 doesn't respond to any i2c messages before we
write 0x1a to demodulator register 0x62. In my understanding this
should be fixed to demodulator code.
