Netlogic XLP network driver update

Changes are to
- update board and network interface detection logic
- fix reading onboard CPLD in little-endian config
- print NAE frequency conrrectly for Bx chips
- update XAUI config to disable Rx/Tx until interface is up

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.

xlpge : driver for XLP network accelerator

Features:
- network driver for the four 10G interfaces and two management ports
on XLP 8xx.
- Support 4xx and 3xx variants of the processor.
- Source code and firmware building for the 16 mips32r2 micro-code engines
in the Network Accelerator.
- Basic initialization code for Packet ordering Engine.

Support for EEPROM and CPLD on XLP EVP boards.

On XLP evaluation platform, the board information is stored
in an I2C eeprom and the network block configuration is available
from a CPLD connected to the GBU (NOR flash bus). Add support
for both of these.

MIPS XLP platform code update.

* Update the hardware access register definitions and functions to bring
them in line with other Netlogic software.
* Update the platform bus to use PCI even for on-chip devices. Add a dummy
PCI driver to ignore on-chip devices which do not need driver.
* Provide memory and IRQ resource allocation code for on-chip devices
which cannot get it from PCI config.
* add support for on-chip PCI and USB interfaces.
* update conf files, enable pci and retain old MAXCPU until we can support
>32 cpus.

Add MIPS platform files for Netlogic XLP SoC.

Processor, UART, PIC and Messaging Network code. Also add
sys/mips/nlm/hal for on-chip device registers.
