ARM: NSP: Add basic support for Broadcom Northstar Plus SoC

Browse Source 
Broadcom Northstar Plus family of SoCs are used for switching
control and management applications as well as residential
router/gateway applications. The SoC features dual core Cortex
A9 ARM CPUs, integrating several peripheral interfaces including
multiple Gigabit Ethernet PHYs, DDR3 memory, PCIE Gen-2, USB 2.0
and USB 3.0, serial and NAND flash, SATA and several other IO
controllers.
