As discussed elsewhere, please drop "renesas,rzn1".

Rather than using interrupt-parent, please use interrupts-extended,
something like this:
interrupts-extended =
<&gic GIC_PPI 13 (GIC_CPU_MASK_SIMPLE(2) |
IRQ_TYPE_LEVEL_LOW)>,
<&gic GIC_PPI 14 (GIC_CPU_MASK_SIMPLE(2) |
IRQ_TYPE_LEVEL_LOW)>,
<&gic GIC_PPI 11 (GIC_CPU_MASK_SIMPLE(2) |
IRQ_TYPE_LEVEL_LOW)>,
<&gic GIC_PPI 10 (GIC_CPU_MASK_SIMPLE(2) |
IRQ_TYPE_LEVEL_LOW)>;
