iio: adc: adc128s052: Rename channel structs

Browse Source 
The adc128s052 can be used to drive a few other ADCs but the TI's ADCs
it was originally intended for. The TI's IC variants model numbers don't
(trivially) explain the channel configuration (for a reader working with
other than TI's ICs).

Rename the channel configuration structures to explicitly explain they
are used for simple ADCs, having 2, 4 or 8 channels.
