The only dependancy on BLOCK_DEV_INITRD by initramfs is that you will
end up with a /initrd.data file locked in ramfs if you miss the
format.   do_mounts_initrd is needed only for the initrd* globals
at the top, those could be moved.

In short, its easy to remove the depenancy today, there is no magic
sharing of the major number as in the past.
