Add subclass of simplebus for Broadcom XLP
This will override the resource allocation of simplebus, and also merge the resource allocation code which was in xlp_pci.c. With this change the SoC devices that does not have proper PCI resources will be on the FDT simplebus. We can remove sys/mips/nlm/dev/cfi_pci_xlp.c and sys/mips/nlm/dev/uart_pci_xlp.c
