Tuner refactoring broke support of tuners with LNA configurations 1 and 2
for both, analog TV and DVB-T.
Additionally, this patch initializes the saa713x gpios defined by the gpiomask
at driver init to avoid undefined stated at dvb.

There are some restrictions:
- The 2nd DVB-S section will only work if the 1st is configured for DVB-S too.
  so "options saa7134-dvb use_frontend=0,1" won't work.
- Currently it is not possible to set the higher LNB supply voltages, so
  14V instead of 13V in the 2nd section.
- It is not possibe to turn off the 2nd LNB supply independently.
This comes from the problem that the 2nd section can't access the i2c interface
of the LNB supply chip.

In the case of an access error to the high latency registers of
the audio DSP, the interface needs to be cleared, otherwise a cascade
of errors occurs.

This patch is closely modeled after a proposal by Mirek Slugen

As reported by  Roel Kluin <12o3l@tiscali.nl>:

	if ((fmr2->card_type != 11)

I don't understand this '&& V4L2_CID_AUDIO_VOLUME'

CodingStyle on the changed procedures.

tuner-xc2028 needs to know when a DVB module is sharing the same analog tuner.
This is done by comparing a magic number that needs to be the same on analog
and on digital. To make easier, this magic number is a pointer to some data
struct.

With the previous code, two different pointers were using, causing a
miss-detection.

It was being detected as a GENERIC UNKNOWN CARD both by the 2.6.18
kernel and the latest v4l-dvb drivers, but it did not work at all. The
card has sixteen (16) BNC video inputs, four of them on the board itself
and twelve on three daughter-cards. It has a single bt878 chip, no tuner
and what looks like and audio input. After doing some research I managed
to get only eight channels working by forcing card=125 and those DID NOT
match channels 0-7 on the card, and no audio.

Based on what was working for card=125, I added the card definition
block, added a specific muxsel routine and got the card working fully
with xawtv, where the sixteen channels show up as Composite0 to
Composite15, matching the channel labels in the card and daughter-cards.
I have made no efforts yet to get audio working, but would appreciate
any pointers.
