[PATCH v2] eeprom: at24: use of_match_ptr()

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

This driver does not depend on CONFIG_OF so using of_match_ptr() makes
sense to reduce the size a bit.

v1 -> v2:
- use __maybe_unused to avoid warnings about at24_of_match not being used
