realtek: HPE 1920-48G-PoE: allow fan speed control
The JG928A has an RTL8231 on the aux mdio bus. Add it to dts to expose the GPIO pins used to control and monitor the fan speed. To enable speed control, add the appropriate kernel driver module to DEVICE_PACKAGES. Of note, this does not control all fans for the unit. The power supply fans are not controlled.
