chardev: introduce chr_machine_done hook
Introduce ChardevClass.chr_machine_done() hook so that chardevs can run
customized procedures after machine init.
There was an existing mux user already that did similar thing but used a
raw machine done notifier. Generalize it into a framework, and let the
mux chardevs provide such a class-specific hook to achieve the same
thing. Then we can move the mux related code to the char-mux.c file.
Since at it, replace the mux_realized variable with the global
machine_init_done varible.
This notifier framework will be further leverged by other type of
chardevs soon.
