hwmon: (asus-ec-sensors) Fix T_Sensor for PRIME X670E-PRO WIFI

On the Asus PRIME X670E-PRO WIFI, the driver reports a constant value of
zero for T_Sensor. On this board, the register for T_Sensor is at a
different address, as found by experimentation and confirmed by
comparison to an independent temperature reading.

* sensor disconnected: -62.0°C
* ambient temperature: +22.0°C
* held between fingers: +30.0°C

Introduce SENSOR_TEMP_T_SENSOR_ALT1 to support the PRIME X670E-PRO WIFI
without causing a regression for other 600-series boards
