Driver for the EFM32 internal temperature sensor.
All EFM32 chips have an internal ADC input channel that reads the internal temperature sensor. This EFM32-specific driver provides an interface for reading this value, compensated using factory-calibrated values.
The board must define
CORETEMP_ADC to point to the ADC line that connects to the right ADC input channel.
This driver provides [S]ensor [A]ctuator [U]ber [L]ayer capabilities.

Initialize the sensor.
This driver assumes that the
CORETEMP_ADC is defined and points to the ADC input channel that is connected to the internal temperature sensor.
Read the current temperature from the sensor.
Temperature readings are compensated using the factory-calibration values.
