[PATCH v4 3/8] mmc: tmio, sh_mobile_sdhi: Pass tmio_mmc_host ptr to clk_{enable,disable} ops

[Ben Hutchings <ben.hutchings@xxxxxxxxxxxxxxx>]

Change the clk_enable operation to take a pointer to the struct
tmio_mmc_host and have it set f_max.  For consistency, also change the
clk_disable operation to take a pointer to struct tmio_mmc_host.
