758a747566 hw/intc: Set physical cpuid route for LoongArch ipi device

8f30771ce6 hw/loongarch/virt: Add cpu arch_id support 
With acpi madt table, there is cpu physical coreid, which may
be different with logical id in qemu. This patch adds cpu arch_id
support, and fill madt table with arch_id. For the present cpu
arch_id is still equal to logical id.

646c39b220 hw/loongarch/virt: Set max 256 cpus support on loongarch virt machine 
Add separate macro EXTIOI_CPUS for extioi interrupt controller, extioi
only supports 4 cpu. And set macro LOONGARCH_MAX_CPUS as 256 so that
loongarch virt machine supports more cpus.

Interrupts from external devices can only be routed cpu 0-3 because
of extioi limits, cpu internal interrupt such as timer/ipi can be
triggered on all cpus.

fda3f15b00 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.
