Nothing ;)

Slipped through unnoticed, I'll drop it.

There isn't any in arch/arm64/Kconfig.platforms right now, so I didn't
feel like introducing one.  Also the dependency should have pretty much
the same effect ...

Added for consistency.  When we add ARCH_BCM all ARCH_BCM_* should
depend on it ...

We could also do it the other way around: make ARCH_BCM a hidden bool
and have ARCH_BCM_* select it.
