On those machines. On those machines, power fault detected bit in the slot status register was set again immediately when it is cleared in the interrupt service routine, and next power fault detected interrupt was notified again. Therefore, disable power fault detected event notification for now. This patch also removes unnecessary handling for power fault cleared event because this event is not supported by PCIe spec.
