Introduce a new notifier, machine_init_done_late, that is notified after
machine_init_done.  This will be used by TDX to generate the HOB for its
virtual firmware, which needs to be done after all guest memory has been
added, i.e. after machine_init_done notifiers have run.  Some code
registers memory by machine_init_done().

Can you be more specific than "some code"?

I see only pc_memory_init() adding guest ram (and the corresponding e820
entries), and that should run early enough ...
