mmc: tmio: remove SCLKEN bit setting from tmio_mmc_set_clock()

TMIO clock is set via tmio_mmc_set_clock() -> tmio_mmc_clk_start(),
and SCLKEN bit will be set on tmio_mmc_clk_start().
It is not needed on tmio_mmc_set_clock() function.
The required clock setting will not be able to set
in some clocks without this patch.
