Daniel P. Carvalho 1b172fb8d2 drivers/sensors: add Microchip TC74 temperature sensor driver
Add support for the Microchip TC74 digital temperature sensor using the
Sensor Driver Framework (uORB). The TC74 is an 8-bit I2C temperature
sensor with a measurement range from -40C to +125C and a resolution
of 1C.

The driver registers as a uORB topic (/dev/uorb/sensor_temp<n>) and
polls on the low-priority work queue. It supports dynamic interval
configuration and automatically enters low-power standby mode when
the topic is deactivated.

Validated against a real TC74A5-3.3 on a custom STM32H743BI board.
