URL: https://github.com/apache/nuttx/pull/20171

   ## Summary
   - Add a legacy character-device driver for the Microchip TC74 digital 
temperature sensor, following the existing lm75.c pattern
   - Register via tc74_register(devpath, i2c, addr), read via read() returns a 
b16_t fixed-point temperature value; ioctl() covers standby/powerup and 
Fahrenheit/Centigrade reporting
   
   ## Impact
   - New driver only, no changes to existing code paths
   
   ## Testing
   - tools/nxstyle and tools/checkpatch.sh clean
   - Validated against a real TC74A5-3.3 sensor on a custom STM32H743BI board 
(I2C address 0x4D): correct temperature reading confirmed via /dev/temp0
