Cole Robinson e6ad2b69ae qemu: parse: drop redundant AddImplicitControllers 
PostParse handles it for us now.

This causes some test suite churn; qemu's custom PostParse could is
now invoked before the generic AddImplicitControllers, so PCI
controllers end up sequentially in the XML before the generically
added IDE controllers. So it's just some XML reordering
