ARM: BCM53573: Initial support for Broadcom BCM53573 SoCs

Browse Source 
BCM53573 series is a new family with embedded wireless. By marketing
people it's sometimes called Northstar but it uses different CPU and has
different architecture so we need a new symbol for it.
Fortunately it shares some peripherals with other iProc based SoCs so we
will be able to reuse some drivers/bindings.

BCM53573 series is set of SoCs using ARM Cortex-A7 CPUs with wireless
embedded in the chipset.
This SoC line is mostly used in home routers and is some cheaper
alternative for Northstar family.
The base chip is BCM53573 and there are some packaging modifications
like BCM47189 and BCM47452.
