[PATCH soc/next?] ARM: BCM53573: Initial support for Broadcom BCM53573 SoCs

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

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.
