ext4: drop ext4dev compat

Browse source 
Kconfig & super.c promised it'd be gone by 2.6.31, so it's
about time to drop it.

help
Starting with 2.6.28, the name of the ext4 filesystem was
renamed from ext4dev to ext4. Unfortunately there are some
legacy userspace programs (such as klibc's fstype) have
"ext4dev" hardcoded.
To enable backwards compatibility so that systems that are
still expecting to mount ext4 filesystems using ext4dev,
choose Y here. This feature will go away by 2.6.31, so
please arrange to get your userspace programs fixed!
