FMC Carrier should read EEPROM and check/validate module before enabling 12P0V, 3P3V and VADJ.
Therefore IC11 should not be connected directly to Management (I2C, GA0,
PCA9306 like buffers are required.
IC11 is a DAC5578SRGE directly connected to (I2C, GA0, GA1), while it is
powered by P3V3 that may not be present.
