hw/mips/mips_malta: Extract the PIIX4 creation code as piix4_create()
The Malta board instantiate a PIIX4 chipset doing various calls. Refactor all those related calls into a single function: piix4_create(). Reviewed-by: Aleksandar Markovic <amarkovic@wavecomp.com> Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com>
