hw/loongarch: Add support loongson3 virt machine type.
Emulate a 3A5000 board use the new loongarch instruction.
3A5000 belongs to the Loongson3 series processors.
The board consists of a 3A5000 cpu model and the virt
bridge. The host 3A5000 board is really complicated and
contains many functions.Now for the tcg softmmu mode
only part functions are emulated.
