Fansensor: Support ast26xx pwm/tach
Add new fantype for ast26xx tach driver.
Use pwm-fan driver to setup ast26xx pwm driver for easier usage.
User must define pwm-fan node in dts as below
pwm-fanX {
compatible = "pwm-fan";
.......
};
refer Documentation/devicetree/bindings/hwmon/pwm-fan.txt for details
and Connector in EM configuration
"Connector": {
"Pwm": X,
......
}
where X is integer
Tested: On Facebook Bletchley (ast26xx) Platform with 1 fan

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.
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
