hw/riscv: virt: fix DT property mmu-type when CPU mmu option is disabled
The device tree property "mmu-type" is currently exported as either
"riscv,sv32" or "riscv,sv48".
However, the riscv cpu device tree binding [1] has a specific value
"riscv,none" for a HART without a MMU.
Set the device tree property "mmu-type" to "riscv,none" when the CPU mmu
option is disabled using rv32,mmu=off or rv64,mmu=off.
