Use dev_fwnode() on the device instead of getting an fwnode handle of the
device's OF node. The result is the same on OF-based systems and looks
better, too.

The output pixel format changed by set_fmt() pad operation is not
correctly applied. It is intended to be restored by calling
ov5640_set_framefmt() when the video stream is started.
However, when the device is powered on by s_power subdev operation before
the video stream is started, the current output mode setting is restored
by ov5640_restore_mode() that also clears pending_mode_change flag in
ov5640_set_mode(). So ov5640_set_framefmt() isn't called as intended and
the output pixel format is not restored.
This change adds the missing output pixel format setting in the
ov5640_restore_mode() that is called when the device is powered on.

After a framerate update through s_frame_interval(), the new
framerate was not taken into account when streaming,
but was taken into account on next session.
This was due to sensor->current_mode not updated accordingly to new
framerate setting in ov5640_s_frame_interval().

Time to time, stream on is failing with a strange positive error.
Error code is returned erroneously by ov5640_set_ctrl_exposure()
due to ov5640_get_vts() return value wrongly treated as error.
Fix this by forcing ret to 0 after ov5640_get_vts() success call,
in order that ret is set to success for rest of code sequence.

The v4l2_i2c_subdev_init() sets V4L2_SUBDEV_FL_IS_I2C flag in the
subdev->flags. But this driver overwrites subdev->flags immediately after
calling v4l2_i2c_subdev_init(). So V4L2_SUBDEV_FL_IS_I2C is not set after
all.
This stops breaking subdev->flags and preserves V4L2_SUBDEV_FL_IS_I2C.
Side note: According to the comment in v4l2_device_unregister(), this is
problematic only if the device is platform bus device. Device tree or
ACPI based devices are not affected.
