media: atomisp: Remove compat ioctl32 header file

The atomisp_compat_ioctl32() function was deleted in commit b4c650f1
("media: atomisp: remove compat_ioctl32 code"), so this header file is no
longer needed.

Additionally, the definition of atomisp_compat_ioctl32() in atomisp_ioctl.h
is unused as well. Delete the declaration from the header.
