Change the device path representation in libofw to use the full firmware

path, instead of an internal i386 specific one.  Don't try to interpret
a disklabel in ofw_disk.c, open the partition's device node directly and
let the firmware do it.  This fixes booting from a partition other than 'a'
on sparc64, which is needed to support more installation methods.

No objection:	ppc
