Add default responder to bus

Update configuration for new default responder on bus
Update to devices to handle their own pci config space without pciconfigall
Remove most of pciconfigall, it now is a dumbdevice which gets it's address based on the bus it's supposed to respond for
Remove need for pci config space from platform, add registerPciDevice function to prevent more than one device from having same
bus:dev:func and interrupt
Remove pciconfigspace from pci devices, and py files
Add calcConfigAddr that returns address for config space based on bus/dev/function + offset
