Added loongarch UEFI BIOS support to compiled scripts.
UEFI code images require 16M alignment, flash images require
16M alignment, under the loongarch architecture.This is agreed
upon when the firmware is loaded in QEMU under Loongarch.
The naming of UEFI under loongarch refers to the x86 and arm naming methods,
and the UEFI image names in x86 and arm are:
edk2-i386-code.fd
edk2-i386-vars.fd
edk2-arm-code.fd
edk2-arm-vars.fd
So on loongarch, we named it:
edk2-loongarch64-code.fd
edk2-loongarch64-vars.fd

Hello, everyone:
Earlier I submitted a patch that provides support for loongarch efi
compilation in qemu.
However, the loongarch virtual machine UEFI code was in the edk2-platform
repository at the time, and community members did not integrate it because
it would cause the qemu distribution package to be too large.
But now, the UEFI code of loongarch virtual machine has been migrated
from edK2-platform to edk2 repository. The migration work was completed
and merged into edk2 main line on 2024/6/18.
The edk2-stable202408 release will come with support for loongarch,So
I modified my previous patch and submitted it.
Before committing, I successfully compiled(Here I switch the edk2 repository
to the master branch in order to compile and test) the loongarch UEFI firmware
on a fedora39(x86) machine using the compile script in the roms directory in qemu,
and I was able to successfully run it in tcg mode in qemu using
the following command:
qemu-system-loongarch64 -bios edk2-loongarch64-code.fd -serial stdio
Thanks,
Xianglai.

Patch looks good, but should be applied only after updating the edk2 submodule to edk2-stable202408 so we don't break the firmware builds. I'll add the patch to the next edk2 update. take care, Gerd
