hw/riscv/virt.c: add address-cells in create_fdt_one_aplic()

We need #address-cells properties in all interrupt controllers that are
referred by an interrupt-map [1]. For the RISC-V machine, both PLIC and
APLIC controllers must have this property.

PLIC already sets it in create_fdt_socket_plic(). Set the property for
APLIC in create_fdt_one_aplic().
