Stephen Warren ed7481c7d1 ARM: bcm283x: don't always define CONFIG_BCM2835
Currently, CONFIG_BCM2835 is defined for all BCM283x builds and _BCM2836
is defined when building for that SoC. That means there isn't a single
define that means "exactly BCM2835". This will complicate future patches
where BCM2835-vs-anything-else needs to be determined simply.

Modify the code to define one or the other of CONFIG_BCM2835/BCM2836 so
future patches are simpler.
