mmc: tmio: stop clock when 0Hz is requested

Browse source

Setting frequency to 0 is not enough, the clock explicitly has to be
disabled. Otherwise voltage switching (which needs SDCLK to be quiet)
fails for various cards.

Because we now do the 'new_clock == 0' check right at the beginning,
the indentation level of the rest of the code can be decreased a little.
