iio: adc: ad7173: refactor device info structs

Browse Source 
Drop setting .has_temp and .has_input_buf to false in device info struct.
Drop array of device info structs and use individual structs for all;
drop models enum as no longer needed. This improves readability as the
structs are pointed directly.
