Subject: [PATCH] mmc: sdhci: When a UHS switch fails, cycle power if regulator
 is used

Power needs to be removed from the card when switching to 1.8v fails.

If a regulator is used to control vmmc we need to turn the
regulator off and then back on otherwise power will not be
removed from the card.
