GP Timers used as clockevent/source are not available for ti-sysc bus and
handled by Kernel timekeeping core. Now ti-sysc produces error message
every time such timer is detected:
"ti-sysc: probe of 48040000.target-module failed with error -16"
Such messages are not necessary, so suppress them by returning -ENXIO
instead of -EBUSY.
