URL: https://svnweb.freebsd.org/changeset/base/340495

Log:
  - Restore setting the clock for devices which support the default/legacy
    transfer mode only (lost with r321385). [1]
  - Similarly, don't try to set the power class on MMC devices that comply
    to version 4.0 of the system specification but are operated in default/
    legacy transfer or 1-bit bus mode as no power class is specified for
    these cases. Trying to set a power class nevertheless resulted in an -
    albeit harmless - error message.
