hw/loongarch: Refine acpi srat table for numa memory

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 for acpi srat table creation.

loongarch: Change the UEFI loading mode to loongarch

The UEFI loading mode in loongarch is very different
from that in other architectures:loongarch's UEFI code
is in rom, while other architectures' UEFI code is in flash.

loongarch UEFI can be loaded as follows:
-machine virt,pflash=pflash0-format
-bios ./QEMU_EFI.fd

Other architectures load UEFI using the following methods:
-machine virt,pflash0=pflash0-format,pflash1=pflash1-format

loongarch's UEFI loading method makes qemu and libvirt incompatible
when using NVRAM, and the cost of loongarch's current loading method
far outweighs the benefits, so we decided to use the same UEFI loading
scheme as other architectures.

hw/loongarch: Fix ACPI processor id off-by-one error

In hw/acpi/aml-build.c:build_pptt() function, the code assumes that the
ACPI processor id equals to the cpu index, for example if we have 8
cpus, then the ACPI processor id should be in range 0-7.

However, in hw/loongarch/acpi-build.c:build_madt() function we broke the
assumption. If we have 8 cpus again, the ACPI processor id in MADT table
would be in range 1-8. It violates the following description taken from
ACPI spec 6.4 table 5.138:

If the processor structure represents an actual processor, this field
must match the value of ACPI processor ID field in the processor’s entry
in the MADT.

It will break the latest Linux 6.5-rc6 with the
following error message:

ACPI PPTT: PPTT table found, but unable to locate core 7 (8)
Invalid BIOS PPTT

Here 7 is the last cpu index, 8 is the ACPI processor id learned from
MADT.

With this patch, Linux can properly detect SMT threads when "-smp
8,sockets=1,cores=4,threads=2" is passed:

Thread(s) per core: 2
Core(s) per socket: 2
Socket(s): 2

The detection of number of sockets is still wrong, but that is out of
scope of the commit.
