V4L/DVB (8342): sh_mobile_ceu_camera: Add SuperH Mobile CEU driver V3
This is V3 of the SuperH Mobile CEU soc_camera driver.
The CEU hardware block is configured in a transparent data fetch
mode, frames are captured from the attached camera and written to
physically contiguous memory buffers provided by the newly added
videobuf-dma-contig queue. Tested on sh7722 and sh7723 processors.
Changes since V2:
- remove SUPERH Kconfig dependency
- move sh_mobile_ceu.h to include/media
- add board callback support with enable_camera()/disable_camera()
- add support for declare_coherent_memory
- rework video memory limit
- more verbose error messages
Changes since V1:
- fixed the CEU driver to work with the newly updated patches
