Jean-Christop PLAGNIOL-VILLARD 6d803ba736 ARM: 6483/1: arm & sh: factorised duplicated clkdev.c
factorise some generic infrastructure to assist looking up struct clks
for the ARM & SH architecture.

as the code is identical at 99%

put the arch specific code for allocation as example in asm/clkdev.h
