Subject: [PATCH 2/2] Platform/Loongson: Modify loongarch uefi firmware size

After the loongarch flash block size is changed from 128K to 256K,
qemu requires that the UEFI firmware size be aligned with the flash block size(256K).
Otherwise, the firmware cannot be loaded,
Use the following code to resolve the old firmware loading problem:
mv QEMU_EFI.fd  QEMU_EFI.fd-bak
cat QEMU_EFI.fd-bak  /dev/zero | head -c 16m > ./QEMU_EFI.fd
mv QEMU_VARS.fd  QEMU_VARS.fd-bak
cat QEMU_VARS.fd-bak /dev/zero | head -c 16m > ./QEMU_VARS.fd

For the new firmware, we refer to other architecture UEFI and
set the UEFI firmware size to align with the flash block size(256K).

So for this patch, we set the UEFI firmware size to 256K alignment.
