[PATCH v3] arm64: dts: meson: add gpio-fan control to GS-King-X

[Furkan Kardame]

GS-King-X has a single speed GPIO fan which is always-on by default. If we add controls for the fan and a trip point, the fan stays off most of the time, reducing background noise from the unit.

Fixed speed-map indentation, aligned bracket, changed cooling-device and increased temperature to 70°C
