[PATCH v6 1/9] irqchip/sunxi-nmi: add A64 R_INTC to the binding doc

[Icenowy Zheng]

The A31 NMI driver seems to be using wrong base address.

As we're going to convert to use a correct NMI base address (and
correctly name it to R_INTC as the datasheet suggests), add a new
compatible string for the "correct" R_INTC, which we will use for A64
SoC.
