This allows us not to include any additional binaries for bcache support in initrd; just an udev rule.

This patch does two things:
|
|
1) Drops probe-bcache, so now new util-linux detecting functionality is used.
|
|
2) Drops bcache-register, using kmod (built in udev) and moving registering device
|
|
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.
