[media] media: Add stk1160 new driver (easycap replacement)

This driver adds support for stk1160 usb bridge as used in some
video/audio usb capture devices.
It is a complete rewrite of staging/media/easycap driver and
it's meant as a replacement.

As stk1160 allows communication with an ac97 codec chip, this
driver allows to register a control-only sound card to allow the user
to access ac97 controls.

Two devices have been used for testing:
* 1-cvbs video and 1-audio ac97 input,
* 4-cvbs inputs
Both of these devices reports with the same id [05e1:0408],
so the driver tries to support a superset of the capabilities.

By using keep_buffers module parameter it's possible to prevent
the driver from releasing urb buffers when streaming is stopped.
The usage of this parameter can avoid memory fragmentation that may
cause the driver to stop working on low memory systems.
A similar mechanism is implemented in em28xx driver (see commit 86d38d).

[media] xc5000: reset device if encountering PLL lock failure

It's possible for the xc5000 to enter an unknown state such that all
subsequent tuning requests fail.  The only way to recover is to reset the
tuner and reload the firmware.  This problem was detected after several days
straight of issuing tuning requests every five seconds.

Reset the firmware in the event that the PLL is in an unlocked state.  This
solution was provided by the engineer at CrestaTech (the company that acquired
Xceive).

[media] au0828: prevent i2c gate from being kept open while in analog mode

The original implementation of the analog support would use an
i2c_gate_ctrl function when using the digital side of the au8522, but on
the analog side we would always just force the gate open and leave it
open all the time.

This can have adverse effects on the xc5000 given the tuner is receiving
all the spurious i2c traffic (a problem which can be exaggerated due to
bugs in the au0828 i2c hardware implementation).

Rework the existing hack to only open/close the gate when actually
talking to the tuner.

This logic might need to be reworked a bit if anybody ever tries to add
support for a board that has the au0828/au8522 but doesn't have digital
support implemented (because the i2c_gate_ctrl callback is being set in
the DVB attach).  However given how few different models are in
circulation, this can be deferred until such a situation arises (if
ever).
