[PATCH 6/6] arm64: dts: microchip: lan969x: add fan controller

[Robert Marko]

LAN969x provides a PWM fan output and tachometer input in the DEVCPU_GCB
target. Add the fan controller register region to the hardware-monitor
node and use the combined LAN969x hwmon compatible. Declare two PWM cells
for the period and standard polarity flags.

Board-specific fan configuration and pin routing remain in the individual
board device trees.
