With changes to how Hyper-V guest VMs flip memory between private (encrypted) and shared (decrypted), it's no longer necessary to have separate code paths for mapping VMBus ring buffers for for normal VMs and for Confidential VMs. As such, remove the code path that uses vmap_pfn(), and set the protection flags argument to vmap() to account for the difference between normal and Confidential VMs. Signed-off-by:
