powerpc/eeh: Refactor eeh_reset_pe_once()
We shouldn't check that the returned PE status is exactly equal to (EEH_STATE_MMIO_ACTIVE | EEH_STATE_DMA_ACTIVE) but instead only check that they are both set. [benh: changelog] Signed-off-by: Gavin Shan <shangw@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
