iio: adc: ti-ads112c04: Add support for TI ADS112C04

Add IIO driver support for the Texas Instruments ADS112C04 (16-bit)
delta-sigma ADCs.

The driver implements:
- Single-shot conversions using the IIO raw read interface.
- Dynamic parsing of single-ended and differential channels from
  device tree child nodes.
- Hardware interrupt support via the DRDY pin, falling back to
  software polling if no IRQ is provided.
- Per-channel reference source selection (internal 2.048V, external
  REFP/REFN, or AVDD) via the reference-sources device tree property.
  refn-supply is not yet supported.
- Hardware reset via the reset controller framework, falling back to
  the RESET command when no reset controller is present.
