Add driver for ADS7128 and ADS7138 12-bit, 8-channel analog-to-digital
converters. These ADCs have a wide operating range and a wide feature
set. Communication is based on the I2C interface.
ADS7128 differs in the addition of further hardware features, like a
root-mean-square (RMS) and a zero-crossing-detect (ZCD) module.
