After registering the cdev, it would be possible do have an open on it.
In a matter of fact, some versions of udev do this. So, move registration
to the end and protect it with a mutex.

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.
Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

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)

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.
