Chao Li bc518f81fd OvmfPkg: Using the new name of LoongArch CSR 0x20 register
Since the LoongArch SPEC has adjusted the CSR 0x20 register name and
the MdePkg also added the new name, so enable it in OvmfPkg.

Prepare (X86 Linux Environment)

Fedora39 and higher

Install LoongArch64 cross compiler, LoongArch system QEMU.

yum install gcc-loongarch64-linux-gnu
yum install qemu-system-loongarch64

Others X86 OS ENV

Configure cross-tools

Download:

wget https://github.com/loongson/build-tools/releases/download/2023.08.08/x86_64-cross-tools-loongarch64-binutils_2.41-gcc_13.2.0.tar.xz

Configure the cross-tools environment:

mkdir /opt/loongarch64_cross-toolchain/
