[PATCH] arm64: dts: rockchip: Add missing fan-supply to rk3566-quartz64-a

[Diederik de Haas]

The Quartz 64 Model-A Schematic from 20210427 on page 7 shows that the
fan's power supply is provided by VCC12V_DCIN.

This fixes the following warning:

  gpio-fan gpio_fan: supply fan not found, using dummy regulator
