For now it supports only Realtek RTL2831U chip.
RTL2831U is integrated DVB USB interface and DVB-T demod.
DVB-T demod integrated to RTL2831U is Realtek RTL2830.
Supported tuners are QT1010, MT2060 and MXL5005S.

Support for different types of remote.

ITE remotes share common device IDs with differently assigned keys.

Two versions of remote maps have been created there are likely to be more.
v1 for all other IDs
v2 for USB_PID_ITETECH_IT9135_9005.

This patch also separates the configuration parts from it913x_identify_state function.

Control message load increased heavily after CI/CAM support due
to dvb_ca_en50221. It looks like CI/CAM drops to non-working
state easily after error is returned to its callbacks. Due to
that, add some logic to avoid errors repeating failed messages.

As recommended by Jason at ITE, the chip version should select firmware.

However, to continue to support IT9137 firmware with different configuration
the driver will use udev->descriptor.idVendor to select the difference
between IT9135 and IT9137.

This patch introduces no functional changes. It basically defines
a macro for each different req found at the driver, and cleans the
code to use them, making easier to understand the code.

With regards to the IR handling code, although the original code
doesn't define what's the request, it is clear, from the USB logs,
that 0xc5 is for IR polling.

Move the ngene/ddbridge firmware into their drivers.

There are two reasons for that:
	1) The firmware used there didn't work for a few devices
I tested here (Terratec H5, H6 and H7);
	2) At least Terratec H7 doesn't seem to require a firmware
for it to work.

After this change, if firmware is not specified, the driver will
use a rom-based firmware (this seems to be the case for Terratec
H7, although I need to better check the USB dumps to be sure about
that).

In any case, the firmware seems to be optional, as the DRX-K driver
don't return the firmware load error.
