In ptp_ocp_detach() pins resources are freed before ptp_clock_unregister() and it leads to use-after-free during driver removal. Fix it by changing the order of free/unregister calls. To avoid irq handler running on the other core while ptp device unregistering, call synchronize_irq() after HW is configured to stop producing irqs and no irqs are in-flight.
