Temperature sensor

Temperature sensor STLM75M2E is connected to the I2C2 bus of STM32F373VCT6 when
jumpers JP4 and JP5 are set as shown in
EEPROM, Audio codec and DDC on the HDMI_Source connector.
I2C address of temperature sensor is 0b100100(A0). A0 can be 0 or 1 depending on the
setting of SB27.

Note: The temperature result measured from STLM75M2E is slightly higher than ambient
temperature due to board heat.
