Add fan pwm interface target The current daemon only supports RPM-based fan control, whereas the hwmon interface for PWM is often present. This implements the Fan Control PWM dbus interface. This CL is not the complete solution, but if mixed with a follow-on CL that does this, I think it'll be ideal. For instance, this assumes the pwm number matches, whereas the other CL lets you specify the corresponding PWM target for the fan.

Exposes generic hwmon entries as DBus objects.
To build this package, do the following steps:
1. ./bootstrap.sh
2. ./configure ${CONFIGURE_FLAGS}
3. make
To full clean the repository again run `./bootstrap.sh clean`.
To enable the use of Linux features like cgroups prioritization and udev/systemd control, one instance of phosphor-hwmon is intended to be run per hwmon sysfs class instance. This requires an algorithm for selecting a stable, well-known D-Bus busname. The algorithm is <PREFIX>-<ID>.Hwmon<N> where PREFIX is an autoconf configurable prefix (BUSNAME_PREFIX, xyz.openbmc_project by default), ID is a std::hash of the /sys/devices path backing the hwmon class instance, and N is the implemented phosphor-hwmon D-Bus API version.
