This sample application periodically reads raw data from the FDC2X1X
sensor in polling mode or optionally with data ready trigger.
It is able to read the 12-Bit and 28-Bit, as well as the 2-Channel
and 4-Channel versions (FDC2112, FDC2114, FDC2212, FDC2214).
The 4-channel versions are chosen through devicetree properties.
The default is FDC2112.
