Add patches from OPTEE.

This patch is only for ARM64 to support OPTEE virtualization. The patch comes from official OPTEE site https://github.com/OP-TEE/build/blob/4.0.0/br-ext/patches/xen/0001-Set-config-for-OP-TEE.patch Currently Apertis CI/CD does not build for ARM64, but this change has been verified in one of the ApertisPro Projects https://gitlab-apertispro.boschdevcloud.com/apertispro-alt-img/security/main/xen.git and it works fine. So I recommend to merge it to Apertis for the moment since it has no side effect to AMD64 build
