dt-bindings: soc: fsl: qe: Add an interrupt controller for QUICC Engine Ports



The QUICC Engine provides interrupts for a few I/O ports. This is
handled via a separate interrupt ID and managed via a triplet of
dedicated registers hosted by the SoC.

Implement an interrupt driver for it so that those IRQs can then
be linked to the related GPIOs.
