Instead of the legacy behavior where it was required to wait for all

: as soon as the stop_streaming() call is done, abort all DMA transfers,
report the already buffers as failed and return.

[media] media: platform: pxa_camera: make a standalone v4l2 device
This patch removes the soc_camera API dependency from pxa_camera.
In the current status :
- all previously captures are working the same on pxa270
- the s_crop() call was removed, judged not working
(see what happens soc_camera_s_crop() when get_crop() == NULL)
- if the pixel clock is provided by then sensor, ie. not MCLK, the dual
stage change is not handled yet.
=> there is no in-tree user of this, so I'll let it that way
- the MCLK is not yet finished, it's as in the legacy way,
ie. activated at video device opening and closed at video device
closing.
In a subsequence patch pxa_camera_mclk_ops should be used, and
platform data MCLK ignored. It will be the sensor's duty to request
the clock and enable it, which will end in pxa_camera_mclk_ops.
