Using CEU with CSI2 on SH-Mobile requires some special configuration of the
former. We also have to switch from calling only one subdev .s_mbus_fmt and
.try_mbus_fmt to calling all subdevices. Take care to increment CSI2 driver
use count to prevent it from unloading, while in use.

Some SH-Mobile SoCs implement a MIPI CSI-2 controller, that can interface to
several video clients and send data to the CEU or to the Image Signal
Processor. This patch implements a v4l2-subdevice driver for CSI-2 to be used
within the soc-camera framework, implementing the second subdevice in addition
to the actual video clients.

This adds support for the KWorld PlusTV 340U and KWorld UB345-Q ATSC
sticks, which are really the same device. The sticks have an eMPIA
em2870 usb bridge chipset, an LG Electronics LGDT3304 ATSC/QAM
demodulator and an NXP TDA18271HD tuner -- early versions of the 340U
have a a TDA18271HD/C1, later models and the UB435-Q have a C2.
The stick has been tested succesfully with both VSB_8 and QAM_256 signals.
Its using lgdt3304 support added to the lgdt3305 driver by a prior patch,
rather than the current lgdt3304 driver, as its severely lacking in
functionality by comparison (see said patch for details).

Stanse found that in ivtvfb_callback_cleanup and ivtvfb_callback_init
there are unneeded tests for itv being NULL. But itv is initialized
as container_of with non-zero offset in those functions, so it is
never NULL (even if v4l2_dev is). This was found because itv is
dereferenced earlier than the test.
