Change macro name 'LS7A_XXX' to 'VIRT_XXX', as the loongarch
virt machinue use the GPEX bridge instead of LS7A bridge. So
the macro name should keep consistency.

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.

Loongarch virt machine uses general hardware reduces acpi method, rather
than LS7A acpi device. Now only power management function is used in
acpi ged device, memory hotplug will be added later. Also acpi tables
such as RSDP/RSDT/FADT etc.
The acpi table has submited to acpi spec, and will release soon.

Loongarch pch msi intc connects to extioi controller, the range of irq

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.
