Add PTP RX and TX hardware timestamp support on 575XX devices. These devices use the two-step method to implement the IEEE-1588 timestamping support. v2: Add spinlock to serialize access to the timecounter. Use .do_aux_work() for the periodic timer reading and to get the TX timestamp from the firmware. Propagate error code from ptp_clock_register(). Make the 64-bit timer access safe on 32-bit CPUs. Read PHC using direct register access.
