[Xen-devel] [PATCH 19/32] hw/isa/piix4: Move piix4_create() to hw/isa/piix4.c

[Philippe Mathieu-Daudé <philmd@xxxxxxxxxx>]

From: Philippe Mathieu-Daudé <f4bug@xxxxxxxxx>

Now that we properly refactored the piix4_create() function, let's
move it to hw/isa/piix4.c where it belongs, so it can be reused
on other places.
