While at that, do the delay on power/clock enable even if the sensor driver
itself doesn't control the GPIOs. This is required for the OLPC XO-1

In order to receive events generated by subdevices on the video capture
nodes, those events need to be forwarded to the subdevice's list of
reachable video capture devices.

Note this will queue the event to a video device even if there is
no actual _enabled_ media path from the sub-device to the video device.
So a future improvement is to skip the video device if there is no enabled
path to it from the sub-device. The entity->pipe pointer can't be
used for this check because in imx-media a sub-device can be a
member to more than one streaming pipeline at a time.

It is not correct to calculate decoder capture payload dynamically from
the decoded frame width and height reported by the firmware. These tell
us what the decoder wrote into the internal framebuffers. The rotator or
