Daniel DeGrasse 36cc74e7e8 drivers: gpio: gpio_mcux_lpc: add support for module interrupts
On iMX.RT devices, the number of GPIO pins exceeds the maximum of
64 that the PINT interrupt controller can support. Therefore, two
interrupt lines are now shared between the GPIO modules.

This patch allows the user to set the interrupt source for a GPIO
peripheral. For most LPC devices, this will always be the PINT. For some
RT devices, the PINT cannot use pins on GPIO modules other than 0 and 1
as input, and thus the INTA and INTB sources should be used.

Since Zephyr does not support sharing these interrupt between all GPIO
controllers, the user must configure a subset of all GPIO controllers to
use the shared module interrupts. An example of how to do so is provided
for the RT595 EVK.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
