asm-generic: 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.
