drivers: sensor: mb7040: add support for MB7040 ultrasonic sensor

ww3ak · ww3ak · commit 13383bd87856 · 2025-07-04T12:26:31.000+02:00
This commit adds a new driver for the MaxBotix MB7040 ultrasonic
rangefinder. The driver uses I2C communication to read range data
from the sensor and exposes it via the Zephyr sensor API.

Tested on an esp32-s3 board using I2C bus. Verified readings at multiple
distances to confirm accuracy.
