Create a new device tree file for the Broadcom Northstar Plus bcm958622hr SVK. This SVK has 2GB RAM, 5 port Ethernet, 2 PCI slots, and 1 UART. Also, it has the ability to reboot via GPIO. To be added in the future are support for the USB and SLIC audio. Signed-off-by: Jon Mason <jon.mason@broadcom.com> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
