soc: fsl: qe: Add support of IRQs in QE GPIO

Some QE GPIO pins have an associated interrupt line in the QE PIC to
signal state changes on the pin.

Because the GPIO controller does not perform any interrupt handling
itself, a nexus node (interrupt-map) is used to map each GPIO line
supporting IRQ to the parent QE PIC interrupt domain.

Add the to_irq() method in the corresponding GPIO controller driver,
that uses the nexus node to perform the translation.
