Are there enough common cases to make @<path> optional?

For superio it's required.

For cpu and apic on LX boards not so much.

For at least cpu on n-way K8 boards it will be useful again.

The <path> part has to accomodate also complex links and buses.
I guess the patch is already resource-type specific. (acpi has PCI,
superio has ioport..)

What would such a global identifier be used for? One way to identify
something is by position in the dt, but you're asking for a new
"namespace" right?
