[ Upstream commit 58d0d19a204604ca0da26058828a53558b265da3 ]
Since it is perfectly legal to run the kernel at EL1, it is not actually an error if HYP mode is not available when attempting to initialize KVM, given that KVM support cannot be built as a module. So demote the kvm_err() to kvm_info(), which prevents the error from appearing on an otherwise 'quiet' console.
