We don't need yet another subdirectory in arch/arm - yes, that's a
favourite way of avoiding any issues, but really it's not the right
answer.  We already have a place for shared cross-platform code, and
it's called arch/arm/common.

"Drivers go under drivers/" is what we've decided.  If we want to change
that, then we should move all those IRQ, gpio and clock drivers back out
of the drivers/ subtree, because many of them are SoC specific.

Please, think back to why we made the original decision(s) to move this
stuff out of arch/arm.
