powerpc/eeh: Display eeh error location for bus and device
For adapters which have devices under a PCIe switch/bridge it is informative to display information for both the PCIe switch/bridge and the device on which the bus error was detected. rebased to powerpc-next Signed-off-by: Richard A Lary <rlary@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
