Gerson Fernando Budke f93ee9508b soc: arm: cypress: psoc6: Add Cortex-M0+ int mux support
PSoC-6 SoC needs that user define the nvic interrupt number to bind
with the peripheral interrupt line for the Cortex-M0+ CPU.  It uses
a multiplex before any NVIC interrupt line.  The interrupt vector is
selected using interrupt-parent property with the intmux_chN number
reference.

Note: The PSoC-6 SoC allows that both CPUs receive the same interrupt.
A tipical use is GPIO interrupt handle and user is responsable to
define interrupt line, priority and take care of enable same peripheral
instance on both CPUs only when appropriated.
