rockchip: veyron: Set vcc33_sd regulator value

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.
