Define timing macro's for all the available speeds of mmc. This is
done similar to linux. Replace speed macro's used with these new timing
macro's wherever applicable.

(no changes since v2)

Changes in v2:
 - Timing macro's are common to all mmc drivers, hence remove zynq_sdhci
   from subject and description.
