This patch does two things:
1) Drops probe-bcache, so now util-linux detecting functionality is used.
2) Drops bcache-register, moving registering device functionality into rule
using 'sh'.
This reduces things that need to be present in initrd, replacing them with
already existing functionality and reducing overall initrd size.
