Previously, demodulator and tuner attach was done in the
demod_attach callback. Migrate the tuner part in the
tuner_attach callback in ngene_info to do thing in right place.

Currently there are two different implementations (in the firmware) for
the QAM demodulator command: one takes 4 and the other takes 2
parameters. The driver shows an error in dmesg When using the
4-parameter command with firmware that implements the 2-parameter
command. Unfortunately this happens every time when chaning the
frequency (on DVB-C).

This patch simply makes configurable, how many command parameters will
be used. All existing drxk_config instances using the "drxk_a3.mc" were
updated because this firmware is the only loadable firmware where the
QAM demodulator command takes 4 parameters. Some firmwares in the ROM
might also use it. The drxk instances in the em28xx-dvb driver were also
updated to silence the warnings.

If no qam_demod_parameter_count is given in the drxk_config struct, then
the correct number of parameters will be auto-detected.

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.

Currently, the only parameter to be configured is the I2C
address. However, Terratec H5 logs shows that it needs a different
setting for some things, and it has its own firmware.

So, move the addr into a config structure, in order to allow adding
the required configuration bits.

Split out the card profiles into a new file called ngene-cards.c.  This is
part of a larger refactoring of the driver in preparation for adding analog

Note that this patch makes *no* functional change - all I did was cut/paste the
