ads1220: Add input_mux and vref options to ADS1220 sensor (#6713)
* fix type comparison bug that stopped the sensor from initializing
* correct mismatch between docs and code for `sample_rate` (fixed to work same as hx71x)
* add input_mux, pga_bypass and vref options
* update configuration reference & fix typo
