If V4L2_CAP_DEVICE_CAPS is set, then the new device_caps field is filled with
the capabilities of the opened device node.

The capabilities field traditionally contains the capabilities of the physical
device, being a superset of all capabilities available at the several device
nodes. E.g., if you open /dev/video0, then if it contains VBI caps then that means
that there is a corresponding vbi node as well. And the capabilities field of
both the video and vbi nodes should contain identical caps.

However, it would be very useful to also have a capabilities field that contains
just the caps for the currently open device, hence the new CAP bit and field.

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.
