Adds support for Pixelviex Xcapture USB grabber device.
This device has one composite and one s-video entry
only, plus a button.
For now, the button is not supported.

Some devices don't need to use it. So allow to just disable this logic.
Having it enabled on some devices cause power management to complain,
generating error -71.

Instead of per-model tests all over the code, use some parameters
at the board entries to describe the model variants for:
- devices with 417 MPEG encoder;
- devices that use external AV;
- devices where vbi VANC endpoint doesn't work;
- devices with xc5000 that require different IF
initialization (and probably will cover also
xc3028).
- devices with xceive tuner that require a reset
during init.

The check for xc5000 assumes that the tuner will always
be using the same bus and will have the same address.
As those are configurable via dev->board, it should use,
instead, the values defined there.
Also, a similar type of test will be needed by other
tuners (for example, for TUNER_XC2028)

the return -ENODEV to happen before the device register
logic, if the interface is not the audio/video (int 1).

When a device is not detected, the driver prints a warning message.
That's ok, except for the fact that, even on newer devices that have
eeprom but aren't yet supported, it prints a message saying that the
device doesn't have eeprom.
Fix it by having a separate message for devices with eeprom, but not
yet known by the driver.

This driver is abusing the kernel<=>userspace API, due to the lack of a
proper solution for it. A discussion were done at:
http://www.mail-archive.com/linux-media@vger.kernel.org/msg22196.html
But there's not a solution for it yet. So, move the driver to staging, while
we don't have a final solution.

The STV0900 features two demodulator paths in one chip. Thus it is not
possible to use the generic power off function of the chip when sending
one of them to standby. The other path will stop working in that case.
The sleep function now switches off functionality specific to the demod
path. The global stuff is only switched off, when both paths are in
sleep mode. The wakeup function always turns on the global functionality
and then works specific to the path.
