hw/riscv: virt: fix the plic's address cells

Browse Source 
When optional AIA PLIC support was added the to the virt machine, the
address cells property was removed leading the issues with dt-validate
on a dump from the virt machine:
/stuff/qemu/qemu.dtb: plic@c000000: '#address-cells' is a required property
        From schema: /stuff/linux/Documentation/devicetree/bindings/interrupt-controller/sifive,plic-1.0.0.yaml
Add back the property to suppress the warning.
