gpio_qmsi: Add get_pending_int API

Browse source 
For AON peripherals on Quark SE C1000, an API is needed
to retrieve the interrupt status after wake up.
This enables the application to know the wake source before
enabling again the interrupts.
Add this API to the gpio as this is a wake event
on Quark SE C1000.
