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.

Since v1:
- function namings were cleaned into pxac_XXX_YYYY()
- function were regrouped in the 3 big categories :
- device probing/removal : pxa_camera_*()
- videobuf2 : pxac_vb2_*()
- v42l file operations : pxac_vidioc_*()
- internal driver functions : pxa_camera_*() : to be found a cute
pattern for RFC v3
Since v2:
- split functions
- start_streaming() implemented
Since v3:
- conflict in void *alloc_ctxt by struct device *alloc_devs change
- ctrl_handler for video device added
- 2 ioctrl disables removed
- disable sensor module removal, it will be loaded forever ...
