media: v4l: subdev: Switch to stream-aware state functions

Switch all drivers accessing sub-device state to use the stream-aware
functions. We will soon remove the old ones.

Additionally drivers/media/i2c/s5k5baf.c and
drivers/media/platform/samsung/s3c-camif/camif-capture.c have been
manually changed as Coccinelle didn't. Further local variables have been
removed as they became unused as a result of the other changes.

Also Coccinelle introduced indentation by space in files
drivers/media/i2c/st-mipid02.c and
drivers/media/platform/rockchip/rkisp1/rkisp1-isp.c. This has been also
corrected.

media: i2c: og01a1b: Drop system suspend and resume handlers

Stopping streaming on a camera pipeline at system suspend time, and
restarting it at system resume time, requires coordinated action between
the bridge driver and the camera sensor driver. This is handled by the
bridge driver calling the sensor's .s_stream() handler at system suspend
and resume time. There is thus no need for the sensor to independently
implement system sleep PM operations. Drop them.

The streaming field of the driver's private structure is now unused,
drop it as well.

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()

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.

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.
