[PATCH] sparc64: Don't use devspec to determine the OBP path

[Eric Snowberg]

Don't use devspec to determine the OBP path on SPARC hardware.  Within all
versions of Linux on SPARC, the devspec returns one of three values: 
"none", "vnet-port", or "vdisk".  Unlike on PPC, none of these values 
are useful in determining the OBP path.

Before this patch grub-ofpathname always returned the wrong value
for a virtual disk. For example:

% grub-ofpathname /dev/vdiskc2
vdisk/address@hidden:b

After this patch it now returns the correct value:

% grub-ofpathname /dev/vdiskc2
/address@hidden/address@hidden/address@hidden:b
