ARM: dts: Enable interrupt support for cygnus crmu gpio driver
The M0 processor handles interrupts for the always-on CRMU GPIO
controller. Setting the CRMU GPIO driver with the mailbox controller as
the interrupt parent allows the mailbox controller to forward interrupts
from the M0 to the GPIO driver for processing.
