* usdhc2 has a levelshifter on the carrier board Rev. DV1,

* During initialisation this isn't working correctly,
* which causes DAT3 to be driven low towards the SD-card.
* This causes a SD-card enetring the SPI-Mode
* and therefore getting inaccessible until next power cycle.
* As workaround we drive the DAT3 line as GPIO and set it high.
* This makes usdhc2 unusable in u-boot, but works for the
* initialisation in Linux
