hwmon: (aht10) Fix initialization commands for AHT20

Browse source

[ Upstream commit b7497b5a99 ]

According to the AHT20 datasheet (updated to V1.0 after the 2023.09
version), the initialization command for AHT20 is 0b10111110 (0xBE).
The previous sequence (0xE1) used in earlier versions is no longer
compatible with newer AHT20 sensors. Update the initialization
command to ensure the sensor is properly initialized.

While at it, use binary notation for DHT20_CMD_INIT to match the notation
used in the datasheet.
