V4L/DVB (6900): cx23885: enable EZ-QAM mode for Hauppauge WinTV HVR-1800
Add module option 'alt_tuner' disabled by default.
When set to one, the dvb_frontend of HVR1800 will consist of:
s5h1409 demod + tda18271 tuner
When set zero (default), the dvb_frontend of HVR1800 will consist of:
s5h1409 demod + mt2131 tuner
If the tda18271 is used in digital mode, you will not be able to
tune an analog channel at the same time.
