rtc: mxc: use dev_pm_set_wake_irq() to simplify code
With calling dev_pm_set_wake_irq() to set MXC RTC as wakeup source for suspend, generic wake irq mechanism will automatically enable it as wakeup source when suspend, then the suspend/resume callback which are ONLY for enabling/disabling irq wake can be removed, it simplifies the code.
