The ROM images all get deleted as they've been loaded to memory, so we
can't go fetch the reset vector from there. Instead, fetch it from

function tcg_commit_cpu as that wires up memory dispatching.

IIRC this is where the cpu needs to be part of the 3-phase reset process.
ROM gets reset too, but with unspecified ordering wrt the cpu itself.
By delaying the load of the reset vector to the reset_exit phase,
you can always load from rom.
I believe Peter most recently handled a very similar situation with armv7m.
