If fadump is not registered, and no other crash or debug handlers are registered, the powerpc panic handler stops the guest before the generic panic code can push out debug information to the console. Currently, system reset injection causes the guest to silently stop. Stop calling ppc_md.panic in the panic notifier. crash_fadump already does rtas_os_term() to terminate the guest if fadump is registered. Remove ppc_md.panic. Move fadump panic notifier into fadump code.
