Read signal strength using VAR_P_INBAND and apply FEC preferred values.

Note this does not work on IT9137 devices even with dvb-usb-it9135-01.fw
firmware.

Config read_sl allows switch between read signal strength and signal
level.

There appears to be differences in the tuner registers
on earlier IT9135 devices.

Using the current IT9137 settings cause corruptions on
some channels

This patch is in preparation for multi firmware loading and
current unsupported types.

Support for version 2 type chips and other LNA versions of version 1

Scripts may be compressed slightly at a later stage.

TODO
Firmware loader
However, things are a little confusing,  it is not clear that
dvb-usb-it9137-01.fw does not work with version 2 chips
as in recent files both firmwares are the same.

Should be applied to: 8133 Support for single ITE 9135 device.

Fronted and Tuner Driver for ITE IT913x Series with inital support for
IT9137 integrated demodulator and tuner device.

The driver is loosely based on AF9035 series. However, support is not intended for
this device specificity.

The IT9137 tuner has been tested on UHF bands, but VHF has only been simulated.

Possible TODO the tuner sections may be separated from the main driver. All future devices
should use the it913x_fe_script_loader for other tuner devices.
