riscv: dts: allwinner: remove address-cells from intc node

A recent submission [1] from Rob has added additionalProperties: false
to the interrupt-controller child node of RISC-V cpus, highlighting that
the D1 DT has been incorrectly using #address-cells since its
introduction. It has no child nodes, so #address-cells is not needed.
Remove it.
