Subject: sh: clk: fix assignment from incompatible pointer type for ioreadX()

The ioreadX() helpers accept now pointer to const memory so declaration
of read function needs updating.

This fixes build errors like:

    drivers/sh/clk/cpg.c: In function `sh_clk_mstp_enable':
    drivers/sh/clk/cpg.c:49:9: error: assignment from incompatible pointer type [-Werror=incompatible-pointer-types]
        read = ioread8;
