  From: Simon Glass <simon.glass@canonical.com>

Move the file_operations and inode_operations structure definitions
from ext4_uboot.h to include/linux/fs.h where they belong according
to Linux kernel conventions.

Add necessary forward declarations for types used by these structures
(delayed_call, fiemap_extent_info, file_kattr, posix_acl, mnt_idmap,
kstat).
