mx2_camera: Add soc_camera support for i.MX25/i.MX27
This is the soc_camera support developed by Sascha Hauer for the i.MX27. Alan
Carvalho de Assis modified the original driver to get it working on more recent
kernels. I modified it further to add support for i.MX25. This driver has been
tested on i.MX25 and i.MX27 based platforms.
