karo: txul: fix LDO4 output voltage

Currently the LDO4 which supplies the pins of the CSI interface is
programmed for a voltage of 1.8V (default setting for this LDO of the
RN5T567).
Change this to 3.3V to match the specification of the TXUL modules.
Also configure the sleep state voltages for the LDOs.
