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.

The subdev .s_stream() operation shall not be called to start streaming
on an already started subdev, or stop streaming on a stopped subdev.
Remove the check that guards against that condition.

The HTS value cannot be directly compared to the sensor's output
size. It needs to be converted to an absolute time unit.
Additionally, the hblank value need to be modified as it was
previous invalid.

After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
commit 03c835f498 ("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 commit ed5c2f5fd1 ("i2c: Make remove callback return void") drivers
were updated to remove the return value of the remove callback, and
return void.
The OV08x40 was added after this commit but was not compile tested at
the time due to a KConfig issue, and this warning was missed.

Add a V4L2 sub-device driver for Omnivision ov08X40 image sensor.
This is a camera sensor using the I2C bus for control and the
CSI-2 bus for data.
This driver supports following features:
- manual exposure and analog/digital gain control support
- vblank/hblank control support
- test pattern support
- media controller support
- runtime PM support
- support following resolutions:
+ 3856x2464 at 30FPS
+ 1928x1208 at 30FPS
