For other cases, these properties are in the host bridge node. If these
are standard PCI rails, then I think that's where they belong unless we10.22.8.121
define slot nodes.

For a soldered down part I'd expect we'd want both (if the host even
cares) - for anything except a supply that I/O or something else shared
is referenced off there's no great reason why it has to be physically
the same supply going to every device on the bus so each device should
be able to specify separately.

Our developer and reference boards frequently have Mini and half-mini
PCIe sockets (a few exceptions), whereas production boards are mostly
soldered down.

If I resubmit this pullreq  so that it  looks for "vpcie12v-supply"
and "vpcie3v3-supply" in the host node, will that be acceptable for
both of you?
