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/disk@2:b
After this patch it now returns the correct value:
% grub-ofpathname /dev/vdiskc2
/virtual-devices@100/channel-devices@200/disk@2:b
