Don't puprosely overclock the SD bus to 30MHz, make the user
explicltly enable that.  The driver chose to use 60MHz / 2 (30MHz)
most of the time rather than 60MHz / 4 (15MHz) based on the Linux
driver of the time.  This pushes the spec a little in order to not
suffer the penalty of running at 15MHz.  However, when other bus
masters are active in the system, and the user tries 4-wire mode, the
internal bus arbitration would fail with data loss as a result.
