V4L/DVB (6965): tda18271: fix analog tuning regression caused by earlier changeset
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.

V4L/DVB (6952): Add code for autoloading em28xx-alsa, if needed
Older em28xx devices does implement standard Audio Class.
However, on newer devices, this were replaced by a Vendor Class. This
patch autodetects that an em28xx lacks Audio Class and auto-loads
em28xx-alsa, for the devices that implements only a Vendor Class.
For devices with Audio Class, snd-usb-audio module will provide an ALSA
interface.
This patch uses the request_module_async function as defined on cx88-mpeg.c,
originally wrote by Markus Rechberger.

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.

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.
