sh: Add media/soc_camera.h to board setup of Renesas AP325RXA

Other compilation errors were revised by commit of
"sh: ap325rxa: Revert ov772x support"
(08c2f5b4d76f83213e379b12df504269d21c9e7c) but other compilation
errors are given.
We revert this commit and need to add new header(media/soc_camera.h).
This change revises new compilation error.
