[ Upstream commit d3ca2ef0c915d219e0d958e0bdcc4be6c02c210b ]
Originally ptp_ocp driver was not strictly checking flags for external timestamper and was always activating rising edge timestamping as it's the only supported mode. Recent changes to ptp made it incompatible with PTP_EXTTS_REQUEST2 ioctl. Adjust ptp_clock_info to provide supported mode and be compatible with new infra.
While at here remove explicit check of periodic output flags from the driver and provide supported flags for ptp core to check.
