mmc: Fix version check for clock API in sdhci driver

When setting up the clocks in the sdhci driver, the "spec version"
must be masked off.  Otherwise any time the vendor version is not 0,
the check will allways assume the interface is version 3.  This breaks
when the interface is actually version 1 or 2.
