hw/loongarch: Add fdt support
...
Add LoongArch flatted device tree, adding cpu device node, firmware cfg node,
pcie node into it, and create fdt rom memory region. Now fdt info is not
full since only uefi bios uses fdt, linux kernel does not use fdt.
Loongarch Linux kernel uses acpi table which is full in qemu virt
machine.

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
