grub_util_get_grub_dev() returns the corresponding GRUB drive for a given
Linux device.  This can be (hdX), (mdX) or (some-lvm-name).

The question here is how GRUB should treat your multipath device.  If it
is like any normal device, in that the BIOS will report it to GRUB as a
disk, you should arrange grub_util_get_dev_abstraction() to return
GRUB_DEV_ABSTRACTION_NONE.

If it's just an alias for an existing device, we'll probably have to
think this through.

And if it's something fancier like RAID or LVM, it'll take some work to
implement.
