Log message:
support rooting off multipath disks.

if you boot from a disk that ends up behind mpath(4) on sparc64,
it wont be able to resolve it to the actual disk device since a
path driver (eg sym(4)) sits where ofw tells us a disk is.

this diff allows the bootpath code to match on path drivers, and
then asks mpath to swap the path for the disk device.
