ARM: arch-shmobile: Add IMX074 camera sensor data to the AP4EVB platform



Add platform data, necessary to use Sony IMX074 camera sensor with AP4EVB.
Note: this does not work reliably without an API to reserve contiguous and
coherent memory for V4L DMA buffers. Such memory reservation has to be added as
soon as a suitable API becomes available.
