x86/kvm/Kconfig: Ensure CRYPTO_DEV_CCP_DD state at minimum matches KVM_AMD
Prevent a config where KVM_AMD=y and CRYPTO_DEV_CCP_DD=m thereby ensuring that AMD Secure Processor device driver will be built-in when KVM_AMD is also built-in. v1->v2: * Removed usage of 'imply' Kconfig option. * Change patch commit message. Fixes: 505c9e94d832 ("KVM: x86: prefer "depends on" to "select" for SEV") Cc: <stable@vger.kernel.org> # 4.16.x Signed-off-by: Janakarajan Natarajan <Janakarajan.Natarajan@amd.com> Reviewed-by: Brijesh Singh <brijesh.singh@amd.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
