media: Switch i2c drivers back to use .probe()

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
commit 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter")
convert back to (the new) .probe() to be able to eventually drop
.probe_new() from struct i2c_driver.

In the probe path, dev_err() can be replaced with dev_err_probe()
which will check if error code is -EPROBE_DEFER.

i2c: Make remove callback return void

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

i2c: Make remove callback return void

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

media: v4l2-subdev: add subdev-wide state struct

We have 'struct v4l2_subdev_pad_config' which contains configuration for
a single pad used for the TRY functionality, and an array of those
structs is passed to various v4l2_subdev_pad_ops.

I was working on subdev internal routing between pads, and realized that
there's no way to add TRY functionality for routes, which is not pad
specific configuration. Adding a separate struct for try-route config
wouldn't work either, as e.g. set-fmt needs to know the try-route
configuration to propagate the settings.

This patch adds a new struct, 'struct v4l2_subdev_state' (which at the
moment only contains the v4l2_subdev_pad_config array) and the new
struct is used in most of the places where v4l2_subdev_pad_config was
used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config
are changed to instead take v4l2_subdev_state.

The changes to drivers/media/v4l2-core/v4l2-subdev.c and
include/media/v4l2-subdev.h were written by hand, and all the driver
changes were done with the semantic patch below. The spatch needs to be
applied to a select list of directories. I used the following shell
commands to apply the spatch:

dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media"
for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done

Note that Coccinelle chokes on a few drivers (gcc extensions?). With
minor changes we can make Coccinelle run fine, and these changes can be
reverted after spatch. The diff for these changes is:

Add support for the mode 6 for the sensor, this mode uses
3/8 subsampling and 3 horizontal binning.
Aspect ratio is changed.
Split the bin_ratio variable into two parts, one for
width and one for height, as the ratio is no longer preserved
when doing subsampling in this mode.

IMX274 also need external 24Mhz clock and is optional based on

disable these supplies and external clock.

media: i2c: imx274: Fix Y_OUT_SIZE register setting

As per Sony IMX274 Y_OUT_SIZE should be the height of effective
image output from the sensor which are the actual total lines
sent over MIPI CSI to receiver.

So, Y_OUT_SIZE should be same as crop height and this patch fixes it.

The I2C core framework provides a simplified probe framework from commit
b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type").

These drivers do not utilise the i2c_device_id table in the probe, so we
can easily convert them to utilise the simplified i2c driver
registration.
