jailhouse: Add simple debug console via the hypervisor
Jailhouse allows explicitly enabled cells to write character-wise
messages to the hypervisor debug console. Make use of this for a
platform-agnostic boot diagnosis channel, specifically for non-root
cells. This also comes with earlycon support.
