This patch converts cx231xx to the new v4l2 dev/subdev, doing:
 - Conversion of i2c calls to subdev calls;
 - all subdev calls to call_all();
 - Corrected the header file order in cx231xx.h;
 - Added tuner frequency setting.

Setup the i2c clock speed to be definable on a per-board basis.  This allows
us to explicitly set the clock speed to 30 KHz on the 950q, and also gets rid
of code which sets it on a basis of what chip the i2c master is talking to
at any given time (which could have caused issues because i2c slaves should
never receive commands at a clock higher than their supported clock speed).

Any time a struct (especially one not defined by this driver) is
allocated, we MUST zero its underlying storage.  This makes our usage
of the struct predictable and robust against future changes where
fields might be added that we don't know about.  Failing to do this
with tuner_setup left the config field uninitialized which then caused
trouble with the tuner type used for HVR-1950 devices.

soc-camera re-uses struct devices multiple times in calls to device_register(),
therefore it has to reset the embedded struct kobject to avoid the "tried to
init an initialized object" error, which then also erases its name. Now with
the transition to kobject's name for device names, we have to re-initialise the
name before each call to device_register().

pxa_dma_update_sg_tail() is called only once, runs exactly the same loop as the
caller and has to recalculate the last element in an sg-list, that the caller
has already calculated. Eliminate redundancy by merging the two loops and
re-using the calculated pointer. This also saves a bit of performance which is
always good during video-capture.

The last buffer queued will often overrun, as the DMA chain
is finished, and the time the dma irq handler is activated,
the QCI fifos are filled by the sensor.

The fix is to ignore the overrun condition on the last
queued buffer, and restart the capture only on intermediate
buffers of the chain.

Moreover, a fix was added to the very unlikely condition
where in YUV422P mode, one channel overruns while another
completes at the very same time. The capture is restarted
after the overrun as before, but the other channel
completion is now ignored.
