ppc/pnv: introduce Pnv8Chip and Pnv9Chip models

Browse source 
It introduces a base PnvChip class from which the specific processor
chip classes, Pnv8Chip and Pnv9Chip, inherit. Each of them needs to
define an init and a realize routine which will create the controllers
of the target processor. For the moment, the base PnvChip class
handles the XSCOM bus and the cores.
