Instead of the legacy behavior where it was required to wait for all video buffers to be finished by the hardware, use a cancel like strategy : as soon as the stop_streaming() call is done, abort all DMA transfers, report the already buffers as failed and return. This makes stop_streaming() more a "cancel capture" than a "wait for end of capture" semantic.

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.

Convert pxa_camera from videobuf to videobuf2. As the soc_camera was already compatible with videobuf2, the port is quite straightforward.
