mx7dsabresd: Set VLD04 output to 2.8V in PMIC initialization.
This change sets the VLDO4 settings output to 2.8V in PMIC
initialization so that the MIPI DSI/CSI input voltage is 2.8V
as per the schematics. The original code provides an output of
3.3V which violates the voltage mentioned in the schematics.
