rtc_qmsi: Call QMSI 1.4 context save/restore functions.

Browse source 
This commit removes the RTC interrupt masking/unmasking needed after
wake up as that functionality is now available in QMSI 1.4. The QMSI
save/restore functions are called instead.

/* The interrupt router registers are sticky and retain their

* But for wake capable peripherals, if their interrupts are
* configured to be edge sensitive, the wake event will be lost
* by the time the interrupt controller is reconfigured, while
* the interrupt is still pending. By masking and unmasking again
* the corresponding routing register, the interrupt is forwared
* to the core and the ISR will be serviced as expected.
