The attached patch solves all my vdr tuning problems on a dib7000p
nova-t stick as far as I could check within the last weekend.
It disables streaming while tuning, like that the number of faulty TS
packets is reduced.

Call analog_ops.standby during tda18271_set_params, to put the tda8295
in tri-state when tuning digital channels. Otherwise the tda8295 will
interfere with the signal coming from the tda18271 into the digital
demodulator.

Parallel support was not working with the s5h1409 and the Pinnacle HD800i.
This patch fixes the demodulator driver and ensures that all existing
s5h1409 based products configure the demodulator correctly.

An earlier patch, "tda18271: fail table lookups if frequency is out of range"
broke analog support on certain hardware. This patch fixes that problem, by
allowing the RF_CAL byte to be set to the maximum value, in cases of the
frequency being out of range.

Rather than using a pointer, include struct analog_demod_ops directly
inside struct dvb_frontend. This will allow us to use dvb_attach in
the future, along with removing the need to check the ops structure
before having to check the pointer to the method being called.
