Yes -- if you're a sysbus device then your reset method is
called. If you're only a subclass of Device then your reset
method is not called.

I think this is because buses like PCI have specific
reset behaviour (order important between host and
devices, maybe?), so we defer reset to the subclass.

(Reset is a mess anyway.)
