Series ext4l: Add Kconfig options to reduce binary size (part P) |

Add Kconfig option to make POSIX ACL support optional. The acl.c and
acl.h files already have proper #ifdef CONFIG_EXT4_FS_POSIX_ACL guards
with stub functions when disabled.

ACLs require extended attributes, so this option depends on EXT4_XATTR.
It is unlikely to be useful in U-Boot but is included for completeness.
