Instead of centrally enabling and disabling subdevice master clocks in
soc-camera core, let subdevice drivers do that themselves, using the
V4L2 clock API and soc-camera convenience wrappers.

) subdevice drivers must register themselves with the framework.
A bridge driver on the other hand must register notification callbacks,
that will be called upon various related events.

mainly addressed the API itself,
users have been updated to reflect the changes.

media: V4L2: add temporary clock helpers
media: V4L2: support asynchronous subdevice registration
media: soc-camera: switch I2C subdevice drivers to use v4l2-clk
soc-camera: add V4L2
Register the imx074 camera I2C and the CSI-2 platform devices directly
in board platform data instead of letting the sh_mobile_ceu_camera driver
and the soc-camera framework register them at their run-time. This uses
the V4L2 asynchronous subdevice probing capability.

Use the v4l2-async API to support asynchronous subdevice probing,
including the CSI2 subdevice. Synchronous probing is still supported too.

so far only very few systems have been ported to that framework. This patch
adds a set of temporary helpers, mimicking the generic clock API, to V4L2.
Platforms, adopting the clock API, should switch to using it. Eventually
this temporary API should be removed.

Both synchronous and asynchronous imx074 subdevice probing is supported by
this patch.

Comparing to the CCF: AFAICS, they do the same, you're supposed to use
IS_ERR_VALUE() on the clock rate, obtaine

Currently modular V4L2 build with enabled OF is broken dur to the
of_get_next_parent() function being unavailable to modules. Export it to
