Remove obsolete resource assigning functions. IO and MMIO address registers are currently set by amd_initcpuio to cover whole PCI hole under 4G to MMIO and IO 0x0000-0xFFFF is configured to be routed to southbridge already. Use generic PCI and resource allocation functions wherever possible to set northbridge resources.
