time/sched_clock: Export symbol for sched_clock_register() function

Timer drivers could be converted into modules. The different
functions to register the clocksource or the clockevent are already
exporting their symbols for modules, but the sched_clock_register()
function is missing.

Export the symbol so the drivers using this function can be converted
into modules.
