mmc: tmio: move clk_enable/disable out of tmio_mmc_host_probe()
The clock is enabled in the tmio_mmc_host_probe(). It also prevents
drivers from performing platform-specific settings before mmc_add_host()
because the register access generally requires a clock.
Enable/disable the clock in drivers' probe/remove. Also, I passed
tmio_mmc_data to tmio_mmc_host_alloc() because renesas_sdhi_clk_enable()
needs it to get the private data from tmio_mmc_host.
