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.

Rather than using a pointer, include struct analog_demod_ops directly
inside struct dvb_frontend. This will allow us to use dvb_attach in

before having to check the pointer to the method being called.

In my testing yesterday, I was using a scan file tailored specifically
for a unique test situation -- As it turns out, this scan file was bad,
and I will use the one included inside dvb-apps for testing for now on.
I've tested with other ATSC tuners just to confirm, using:
us-ATSC-center-frequencies-8VSB
Anyhow, as it turns out, the tuner-xc2028 *does* require a tuning offset
for ATSC. Even though the linux-dvb api passes in center frequencies
from userspace, apparantly the xceive firmware is already factoring in
the tuning offset to center.
In order to make the device function using the same scan files /
channels.conf configurations as other atsc devices, we must offset by
1.75 MHz.

and update set_parameters/get_parameters with the new knowledge.

It seems that the DTV78 firmware is intended for use in locations where
VHF channels have 7MHz bandwidth and UHF channels have 8MHz bandwidth.
If we switch to DTV78 firmware when we detect this condition, we can
avoid firmware reloads when switching between VHF and UHF transponders.
Place the state for this in the control structure so that card drivers
can hint to us to use DTV78 firmware from the first tuning attempt.

When searching for the right S-Code table to load, check the HAS_IF flag
against the firmware we are checking instead of against the the "type"
requested. We already ignore the scode type requested if the caller passed
an int_freq; this makes the search by frequency consistent with that behaviour.
