[PATCH v2 8/8] ARM: bcm2835: Add Kconfig support for bcm2836

[Eric Anholt]

This should be a complete port of bcm2835 functionality to bcm2836
(Raspberry Pi 2).

Signed-off-by: Eric Anholt <eric@xxxxxxxxxx>

v2: Implement Arnd's feedback to not split to ARCH_BCM2836, and
    instead use more conditionals in ARCH_BCM2835.  Also reduce diff
    between 2835 and 2836.
