Based on experiments by Eric Wescott, edit the Sony GigaPocket (Kikyou)
card entry video and audio mux settings.

This is a slightly modified version of Eric Anderson's original patch
for the Sony Giga Pocket board.  It has been updated to apply to the
latest ivtv driver version by Hans Verkuil <hverkuil@xs4all.nl> and
Andy Walls <awalls@radix.net>.  Also Andy Walls modified the patch to
use a new Sony BTF-Pnx01Z tuner entry based on Eric Anderson's experimental
findings for the bandswitch.

>From Eric Anderson's original email:

1. The tuner on the card doesn't seem to match any standard
ones. I modified an existing tuner entry. Ideally a new tuner
entry should be created. (The only difference from the one I
modified is that the low-to-mid range frequency cut-off is
slightly different, as are the bit config settings.)

2. It wasn't obvious how to choose a second audio input other
than using "radio" as an option. Basically there's two GPIO
audio inputs. Using radio allowed me to avoid major restructuring
to the code. (perhaps other cards don't have this often...)

3. It's not clear that there's a mute setting that works. Not
sure why.

4. I haven't had a chance to test the two Svideo inputs. I set
them to COMPOSITE1 and SVIDEO2, but I'm not sure those are the
correct settings. The standard composite video inputs seem to work.

ivtv_api_get_data() was performing more PCI MMIO than needed, resulting
often in it accounting for more than half the total time spent in
ivtv_irq_handler().  Now it only reads at most 7 of the 16 mailbox data words
over the PCI bus, and in some instances only 2 or 3 data words as needed.

After implementing a 300msec wait between digitizer start and encoder

before configuring the encoder.  This reduces the wait period from

Martin Dauskardt <martin.dauskardt@gmx.de> has determined that the
encoder has a much better chance of starting cleanly if we
deliberately hold off starting it util the video digitizer has had a
chance to run for at least 300msec first.  These changes implement an
enforced 300msec wait in the state machine that orchestrates streaming
start / stop.

v4l2_device_register needs to be called before the i2c subdevs are loaded.
However, it was called afterwards in the saa7146 driver. This caused an oops
when loading the mxb and hexium drivers. The vv_init function is now split
into two: one registers the v4l2_device, the other does the rest of the
initialization. The three drivers that depend on this have been updated to
call the new vv_devinit function.
