riscv: dts: sophgo: 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 new cv1800b DT has been incorrectly using #address-cells.
It has no child nodes, so #address-cells is not needed. Remove it.
