[Skiboot] [PATCH 2/8] hw/phb4: Look for the hub-id from in the PBCQ node

[Oliver O'Halloran]

The hub-id is stored in the PBCQ node rather than the stack node so we
never add it to the PHB node. This breaks the lxvpd slot lookup code
since the hub-id is encoded in the VPD record that we need to find the
slot information.
