as refer in this patch "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% in linux move it also as preparing for the SH adding Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
