From: Bernhard Beschow <shen...@gmail.com>
Rather than registering the reset handler via a function which
appends the handler to a global list, prefer to implement it as
a virtual method - PIIX4 does the same already.
Note that this means that piix3_reset can now also be called writing to
the relevant configuration space register on a PCI bridge.
