the second round removes the prepare_stream callback and instead lets the
intermediate subdevices propagate s_stream calls to their sources rather
than individually calling s_stream on each subdevice from the bridge driver.
This is similar to how drm bridges recursively call into their next neighbor.
It makes it easier to do bringup ordering on a per-link level, as long as the
source preparation can be done at s_power, and the sink can just prepare, call
s_stream on its source, and then enable itself inside s_stream. Obviously this
would only work in a generic fashion if all asynchronous subdevices with both
inputs and outputs would propagate s_stream to their source subdevices.

Changes since v1:
 - Propagate field and colorspace in ipucsi_subdev_set_format.
 - Remove v4l2_media_subdev_prepare_stream and v4l2_media_subdev_s_stream,
   let subdevices propagate s_stream calls to their upstream subdevices
 - Various fixes (see individual patches for details)
