drm/imx: ipu-v3 fixups and grayscale support

Browse Source 
- Make const interrupt register arrays static, reduces object size.
 - Fix device_node leaks in PRE/PRG phandle lookup functions.
 - Add 8-bit and 16-bit grayscale buffer support to ipu_cpmem_set_image,
 - add 10-bit and 12-bit grayscale media bus support to ipu-csi,
   to be used by the imx-media driver.
