This patch adds support for PT3 PCIe cards.
PT3 has an FPGA PCIe bridge chip, a TC90522 demod chip and
a VA4M6JC2103 tuner module which contains two QM1D1C0042 chips for ISDB-S
and two MxL301RF's for ISDB-T.
It can receive and deliver 4 (2x ISDB-S, 2x ISDB-T) streams simultaneously,
and a kthread is used per stream to poll incoming data,
because PT3 does not have interrupts.
As an antenna input for each delivery system is split in the tuner module
and shared between the corresponding two tuner chips,
LNB/LNA controls that the FPGA chip provides are (naturally) shared as well.
The tuner chips also share the power line in the tuner module,
which is controlled on/off by a GPIO pin of the demod chip.
As with the demod chip and the ISDB-T tuner chip,
the init sequences/register settings for those chips are not disclosed
and stored in a private memory of the FPGA,
PT3 driver executes the init of those chips on behalf of their drivers.

Refactor and clean up the tw68 driver. It's now using the proper
V4L2 core frameworks.
Tested with my Techwell tw6805a and tw6816 grabber boards.

Now that the custom motion detection API has been replaced with a
standard API there is no reason anymore to keep it in staging.
So (finally!) move it to drivers/media/pci.

As USB/PCI/MEDIA_SUPPORT dependencies can be tristate, we can't
simply make the bool menu to be dependent on it. Everything below
the menu should also depend on it, otherwise, we risk to allow
building them with 'y', while only 'm' would be supported.
So, add an IF just before everything below, in order to avoid
such risks.

Rename all PCI drivers with their own directory under
drivers/media/video into drivers/media/pci and update the
building system.

b2c2 is, in fact, 2 drivers: one for PCI and one for USB, plus
a common bus-independent code. Break it accordingly.
