The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the
beginning of the declaration specifiers in a declaration is an
obsolescent feature.

Toggle the AI1 mux when changing the CX18_AUDIO_ENABLE register.  It's hard to
reliably tell when we have written to this register successfully unless we
change some bits we know we can read back.  The AI mux bits always read back
what we wrote to them, so force them to toggle whenever we have to write to
the register, so we can tell we wrote to the register successfully.

This change was prompted by users experiencing broadcast audio decoding
problems after the cx18 module loads for the first time.

Add code to verify the cx18-av-core digitizer firmware loads correctly.  The
verification function reads back and compares the firmware bytes loaded
into the A/V core.  The result of the verification is only used to log a
message in the system log.

This change was prompted by users with multiple card setups that have problems
with broadcast audio decoding the first time the cx18 module is loaded.

Both the MPEG-2 SVCD stream format and the MPEG-2 DVD stream format should
use an MPEG-2 PS container.  This makes it safe to stuff IVTV Private Stream 1
VBI packets in these stream types using the existing cx18 driver routines.

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.

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.

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.

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.
