[PATCH v2 2/8] mmc: Define timing macro's

[Michal Simek]

From: Ashok Reddy Soma <ashok.reddy.soma at xilinx.com>

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.

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