If a subdevice pad op is called from a bridge driver, then there is
no v4l2_subdev_fh struct that can be passed to the subdevice. This
made it hard to use such subdevs from a bridge driver.
This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config
pointer in the pad ops. This allows bridge drivers to use the various
try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it
along to the pad op.
The v4l2_subdev_get_try_* macros had to be changed because of this, so
I also took the opportunity to use the full name of the v4l2_subdev_get_try_*
functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do
'git grep v4l2_subdev_get_try_format' you will actually find the header
where it is defined.
One remark regarding the drivers/staging/media/davinci_vpfe patches: the
*_init_formats() functions assumed that fh could be NULL. However, that's
not true for this driver, it's always set. This is almost certainly a copy
and paste from the omap3isp driver. I've updated the code to reflect the
fact that fh is never NULL.

The get_unaligned_le*() functions return the value using cpu endianness,
so calling le*_to_cpu is wrong.
It hasn't been not noticed because this code has only been run on little
endian systems, so le*_to_cpu doesn't do anything.

In order to have subsytem agnostic media bus format definitions we've
moved media bus definitions to include/uapi/linux/media-bus-format.h and
prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT.
Replace all references to the old definitions in i2c drivers.

This patch adds driver for Samsung S5K4ECGX image sensor with an
embedded SoC ISP. The driver only implements preview operation mode
and still capture (snapshot) and face detection features are missing
now. Following controls are supported: contrast, saturation,
brightness, sharpness.
