drivers: interrupt: pint: Add API to get pin used IRQ slot

Browse Source 
PINT connects GPIO pin to seperate IRQ slot. This info is
hidden in PINT driver, there is no way to know which IRQ
actually the GPIO pin is connected to.
Add new API to get which IRQ slot is connected to, based on
pin index.
