One LoongArch virt machine platform, there is limitation for memory
map information. The minimum memory size is 256M and minimum memory
size for numa node0 is 256M also. With qemu numa qtest, it is possible
that memory size of numa node0 is 128M.

Limitations for minimum memory size for both total memory and numa
node0 is removed here, including acpi srat table, fadt memory map table
and fw_cfg memory map table.

Also remove numa node about memory region, there is only low memory
region and how memory region.

---
v2 ... v3:
  1. Modify numa test case for loongarch system.
  2. Rebase the patch based on the latest version.

v1 ... v2:
  1. Refresh the patch based on the latest qemu version, solve the
confliction issue.
  2. Add numa test case for loongarch system.
