Subject: [PATCH] clkdev: Add default clkdev.h
Ease the deployment of clkdev by providing a default asm/clkdev.h for
use if the arch does not have an include/asm/clkdev.h.
Due to limitations in Kbuild we manually add clkdev.h to all
architectures that don't have one rather than having the header appear
by default.

Resending as the addition of exec.h introduce a bunch of conflicts, plus
I spotted a typo.
