Thanks. I tested your patch with i386-softmmu (bios only)
and with mipsel-softmmu (debian boot / malta).

All registered reset functions were called only once,
and qbus_reset_all_fn was the last one called.

I noticed that there are two functions named piix3_reset.
One might be renamed to piix3_ide_reset, but this is
not related to your patch. There are also two functions
piix4_reset.
