V4L/DVB (6875): tuner-xc2028: ATSC requires 1.75 MHz tuning offset

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.

V4L/DVB (6855): xc2028: select DTV78 firmware if tuning 7MHz VHF / 8MHz UHF

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.
