Alexandre Belloni 51218298a2 alarmtimer: Ensure RTC module is not unloaded ...

When registering the rtc device to be used to handle alarm timers,
get_device is used to ensure the device doesn't go away but the module can
still be unloaded.

Call try_module_get to ensure the rtc driver will not go away.
