Dave Stevenson 7838c7a9e2 dt-bindings: interrupt-controller: brcm,bcm2836-l1-intc: Drop interrupt-controller requirement
Since commit 88bbe85dcd ("irqchip: bcm2836: Move SMP startup code to
arch/arm (v2)") the bcm2836-l1-intc block on bcm2711 is only used as a
base address for the smp_boot_secondary hook on 32 bit kernels. It is
not used as an interrupt controller.

Drop the binding requirement for interrupt-controller and interrupt-cells
to satisfy validation on this platform.

description:
The BCM2836 has a per-cpu interrupt controller for the timer, PMU
events, and SMP IPIs. One of the CPUs may receive interrupts for the
peripheral (GPU) events, which chain to the BCM2835-style interrupt
controller.
