iio: adc: adc128s052: Support ROHM BD7910[0,1,2,3]
The ROHM BD79100, BD79101, BD79102, BD79103 are very similar ADCs as the
ROHM BD79104. The BD79100 has only 1 channel. BD79101 has 2 channels and
the BD79102 has 4 channels. Both BD79103 and BD79104 have 4 channels,
and, based on the data sheets, they seem identical from the software
point-of-view.
