sh: clock / CPG ioremap() update

[PATCH 01/04] sh: extend clock struct with mapped_reg member [PATCH 02/04] sh: use ioread32/iowrite32 and mapped_reg for mstp32 [PATCH 03/04] sh: use ioread32/iowrite32 and mapped_reg for div4 [PATCH 04/04] sh: use ioread32/iowrite32 and mapped_reg for div6

These patches extend the drivers/sh/clk/ code to use ioremap(). Needed for the soc / board support code for r8a7779. Other SoCs should just keep on working as before.
