Alex Elder 7b5fe9c911 ARM: bcm: config option for l2 cache support
Add a new config option ARCH_BCM_MOBILE_L2_CACHE that allows support
for level-2 cache to be enabled or disabled at build time for
BCM218XX and BCM21664 family SoCs.

Build support for SMC only if it's required (currently it's only
required for to support level 2 cache control).

If arch/arm/mach-bcm/kona.c gets compiled, ARCH_BCM_MOBILE_L2_CACHE
must have been selected, which implies CONFIG_CACHE_L2X0 is set.
There is therefore no need to check CONFIG_CACHE_L2X0 at the top
of kona_l2_cache_init(), so get rid of that check.

Support for Broadcom BCM470X and BCM5301X SoCs with ARM CPU cores.
This is a network SoC line mostly used in home routers and
wifi access points, it's internal name is Northstar.
This inclused the following SoC: BCM53010, BCM53011, BCM53012,
BCM53014, BCM53015, BCM53016, BCM53017, BCM53018, BCM4707,
BCM4708 and BCM4709.
Do not confuse this with the BCM4760 which is a totally
different SoC or with the older BCM47XX and BCM53XX based
network SoC using a MIPS CPU, they are supported by arch/mips/bcm47xx
