[PATCH v2] hwmon: tmp102: Add support for TMP110 and TMP113 devices

[Flaviu Nistor]

TMP110 and TMP113 temperature sensors are software compatible
with TMP102 sensor but have different accuracy (maximum error).

Changes in v2:
- Drop the binding change since no ACK from devicetree maintainer.
- Update only the Kconfig and documentation.
- Link to v1: https://lore.kernel.org/all/20250915170819.126668-1-flaviu.nistor@gmail.com/
