On the veyron board the vcc33_sd regulator is used as vmmc-supply for the SD card. This regulator is powered in the MMC core during power on but its value is never actually set.
In the veyron platform the reset value for the LDO output is 1.8V while the standard (min and max) value for this regulator defined in the DTS is 3.3V. When the MMC core enable the regulator without setting its value, the output is automatically set to 1.8V instead of 3.3V.
With this patch we preemptively set the value to 3.3V.
