Introduce two new ioctl commands, PTP_SYS_OFFSET_PRECISE_CYCLES and PTP_SYS_OFFSET_EXTENDED_CYCLES, to allow user space to access the raw free-running cycle counter from PTP devices. These ioctls are variants of the existing PRECISE and EXTENDED offset queries, but instead of returning device time in realtime, they return the raw cycle counter value.
