[PATCH 3/8] ARM: ux500: Specify the ux5x0 MMCI regulator's on/off GPIO as high-enable

Lee Jones lee.jones at linaro.org

If not specified, the GPIO control bit is inverted by default i.e.
low-enable and high-disable. This is not the case with the MMCI
regulator, hence it will turn on during a disable and off when
regulator_enable() is invoked.
