Subject: [PATCH 3/5] x86/kvm/Kconfig: Have KVM_AMD_SEV select ARCH_HAS_CC_PLATFORM

From: "Borislav Petkov (AMD)" <bp@alien8.de>

The functionality to load SEV-SNP guests by the host will soon rely on
cc_platform* helpers because the cpu_feature* API with the early
patching is insufficient when SNP support needs to be disabled late.

Therefore, pull that functionality in.
