V4L/DVB (11619): cx18: Simplify the work handler for outgoing mailbox commands
Simplify the way outgoing work handler gets scheduled to send empty buffers
back to the firmware for use. Also reduced the memory required for scheduling
this outgoing work, by using a single, per stream work object.

V4L/DVB (11618): cx18: Convert per stream mutex locks to per queue spin locks
To avoid sleeps in providing buffers to user space and in handling incoming
buffers from the capture unit, converted the per stream mutex for locking
queues to 3 spin locks. There is now a spin lock per queue
to increase concurrency when moving buffers around.
Also simplified queue manipulations and buffer handling of incoming buffers
of data from the capture unit.

When sending an outgoing firmware command, prepare to wait before we raise the
interrupt, so we don't miss the wake_up() on the acknowledgment. When waiting
for the acknowledgement, there is no need to loop around schedule(), as there
will only be one interrupt, and hence one wake_up(), issued.

V4L/DVB (11616): cx18: Add a work queue for deferring empty buffer handoffs to the firmware
This change defers sending all CX18_CPU_DE_SET_MDL commands, for a stream with
an ongoing capture, by adding a work queue to handle sending such commands when
needed. This prevents any sleeps, caused by notifying the firmware of new
usable buffers, when a V4L2 application read() is being satisfied or when
an incoming buffer is processed by the cx18-NN-in work queue thread.

V4L/DVB (11611): soc-camera: link host drivers after clients
With the transition of soc-camera to become a platform driver and to the
v4l2-subdev framework the initialisation order becomes important. In case
of a static build clients (i2c) drivers have to be available when host
drivers are probed. Moving host drivers down in the Makefile achieves the
desired order.
Embed struct soc_camera_host in platform-specific per host instance objects
instead of allocating them statically in drivers, use platform_[gs]et_drvdata
consistently, use resource_size().
V4L/DVB (11607): soc-camera: add a free_bus method to struct soc_camera_link
Currently pcm990 camera bus-width management functions request a GPIO and never
free it again. With this approach the GPIO extender driver cannot be unloaded
once camera drivers have been loaded, also unloading theb i2c-pxa bus driver
produces errors, because the GPIO extender driver cannot unregister properly.
Another problem is, that if camera drivers are once loaded before the GPIO
extender driver, the platform code marks the GPIO unavailable and only a reboot
helps to recover. Adding an explicit free_bus method and using it in mt9m001
and mt9v022 drivers fixes these problems.

Here comes the full support for AVerMedia Cardbus Plus (E501R) - including
