Currently CONFIG_ARCH_BCM_MOBILE is used to select all (both)
Broadcom mobile SoC families. Instead, use that only as a config
menu switch, and define specific symbols like ARCH_BCM_281XX to
select a particular SoC family. If ARCH_BCM_MOBILE is selected, all
of the SoCs will be selected by default, but this way each can be
disabled individually as well.
Note that BCM281xx and BCM21664 both require the SMC and L2 cache
control code, so that code will be built based on ARCH_BCM_MOBILE.

v4: Rebased on to of v3.15-rc1. Small tweak in Makefile.
v3: SMC and L2 cache code is needed by both SoC families.
v2: No longer uses Kbuild's $(<modulename>-y) variable mechanism.
The patch is available here:

Applied to mach-bcm for-3.16/cleanup [added ARM: to patch title].
