hwmon: emc2305: Support configurable fan PWM at shutdown
Some systems require fans to enter in a defined safe state during system
shutdown or reboot handoff.
Add support for the optional Device Tree property "fan-shutdown-percent"
to configure the shutdown PWM duty cycle per fan output.
If the property is present for a fan channel, the driver converts the
configured percentage value to the corresponding PWM duty cycle and
applies it during driver shutdown.
If the property is not present, the fan state remains unchanged.
