prep: Use pc87312 device instead of collection of random ISA devices
We can't however replace the built-in IDE controller, as the one in
pc87312 is only single-channel and can use only IRQ 14. Therefore the
pc87312's IDE function gets disabled via the config property.
PReP emulation also gains a parallel port emulation this way.
