V4L/DVB (11063): au8522: power down the digital demod when not in use

When the au8522 is idle, put the chip into a low power mode (reduces power
consumption from 450ma to 346ma)

Thanks to Michael Krufky <mkrufky@linuxtv.org> and Steven Toth
<stoth@linuxtv.org> for providing sample hardware, engineering level support,
and testing.
