Kuninori Morimoto f5942c7621 ARM: shmobile: add struct clk_ratio and fixed ratio clock macro
Renesas chip has many clocks inside,
and some of them are using fixed ratio via parent clock.
Current shmobile clock code is using own divX_recalc function
and divX_clk_ops.
This patch can reduce these code
