cfm: allow setting of max pwm

When a change from xyz.openbmc_project.Control.CFMLimit
interface is detected set the max pwm in pid control configs
to limit max fan speed.

This also puts the max CFM on d-bus for other commands to
use.

Tested-by: Used settingsd to control fan speed

dbus-sensors

dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.

key features

  • runtime re-configurable from d-bus (entity-manager or the like)

  • isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible

  • async single-threaded: uses sdbusplus/asio bindings

  • multiple data inputs: hwmon, d-bus, direct driver access
