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.
