parisc: advertise PCI devs after "assign_resources"
Alex Chiang asked me why PARISC was calling pci_bus_add_devices() and pci_bus_assign_resources() in the opposite order from everyone else. No reason and I couldn't see any data dependency. Patch below applies cleanly to 2.6.30-rc2. Later, I suspected the code worked only because no drivers would be loaded/ready until much later in the system initialization sequence. Tested "LBA" code on J6000 (32-bit) and A500 (64-bit SMP) with 2.6.30-rc2. Not tested with any Dino controllers. Not tested with PCI-PCI Bridge (TBD).
