There are several boards on V4L that can work with several different
helper modules for audio/video encoding/decoding and similar stuff.
This patch adds the capability of choicing between autoselecting the
pertinent helper modules for each driver, or to manually selecting
them.

Several audio/video encoders/decoders were just bound as if they were 
part of the core driver.
In fact, they are generic enough to be used by other drivers as well, 
since they use I2C event bus to communicate.

when checking the -Wextra signedness warnings issued by gcc 4.1
I came across this one:
drivers/media/video/vivi.c:1001: warning: comparison of unsigned expression < 0 is always false
Since videobuf_reqbufs() returns negative values on errors the current
code does no real error checking since gcc removes the comparison.
This patch fixes this issue by making ret a normal, signed integer.

Several changes at register stuff were done since commit
b45009b0, but I've forgot
to add the copyright line for this. Those changes allowed
cx88 to have multiple tuners, allowing it to support hardware with
separated radio and video tuners. It also allows binding a tuner to an
specific i2c address.

cx88-alsa can be compiled in (in distro built kernels, for example), but
not used. In those cases, the audio DMA restart is needed for proper sound
on NICAM channels.
This patch enables the DMA restart even with ALSA, but the functions now
check if cx88-alsa is really active.

If the FX2 does not reset properly during reboot, it can present an
invalid USB device ID and fail to attach.  Prevent this situation
from occuring by resetting the USB part of the card when the PCI part
probes.
Also fix the GPIO configurations so that analog capture will not
inadvertantly reset the USB part.

1) It sets LNBDCPol differently based on the card type. Now it should
work properly for both the kworld and geniatech cards.
2) It stops returning an error for the SEC_VOLTAGE_OFF voltage command
(the cx88-dvb level handles the actual voltage on/off, but it still
passes the ioctl down to the cx24123 level, which previously rejected
the OFF as invalid so the ioctl would report failure)
