hw/riscv/virt.c: use s->memmap in create_fdt_sockets() path

Browse source 
create_fdt_sockets() and all its fdt helpers (create_fdt_socket_aplic(),
create_fdt_imsic(), create_fdt_socket_plic(), create_fdt_socket_aclint()
and create_fdt_socket_memory()) can use s->memmap from their
RISCVVirtState pointer instead of having an extra memmap argument.
