As Ben suggested, it's meaningful to dump PE's location code for site engineers when hitting EEH errors. The patch introduces function eeh_pe_loc_get() to retireve the location code from dev-tree so that we can output it when hitting EEH errors. If primary PE bus is root bus, the PHB's dev-node would be tried prior to root port's dev-node. Otherwise, the upstream bridge's dev-node of the primary PE bus will be check for the location code directly.
