rtc/pxa: remove unnecessary private ops->ioctl() 



We shouldn't implement private ops->ioctl() unless absolutely necessary.
pxa series RTC driver's ioctl() is unnecessary, since RTC subsystem has
implement the ioctl() very well,so we can only use the API of
'.alarm_irq_enable' and '.update_irq_enable' to do enable irq action.
