Thanks!

So either I do it like this by using select FOO in the
Kconfig for the affected SoC, or I just turn it around
and make it depend on the affected SoC and select it
to "y" default.

It's like eating eggs from the little or big end or something.

This current approach has the upside of not proliferating
the SoC Kconfig symbol outside of the ARM tree, but
I have no strong preference...

All this stuff used to live in the arch/arm/mach-foo
folders in the past, like the clocks you just have to
default-enable it somehow.
