ARM: 6526/1: mmci: corrected calculation of clock div for ux500

The Ux500 variant of this block has a different divider.
The value used right now is too big and which means a loss
in performance. This fix corrects it. Also expand the math
comments a bit so it's clear what's happening. Further
the Ux500 variant does not like if we use the BYPASS bit,
instead we are supposed to set the clock divider to zero.
