freebsd-dev/sys/mips/nlm/dev/uart_pci_xlp.c
Jayachandran C. 250a191260 XLP UART code udpate.
Move XLP PCI UART device to sys/mips/nlm/dev/ directory.  Other
drivers for the XLP SoC devices will be added here as well.
Update uart_cpu_xlp.c and uart_pci_xlp.c use macros for uart port,
speed and IO frequency.
