From 4186efb290fedef83cf5f396d655fadcc09d6f47 Mon Sep 17 00:00:00 2001

Subject: Add hwmon systemd unit and udev rule

The udev rule invokes phosphor-hwmon with the
devicetree path of the hwmon device.

The systemd unit is a templated on the devicetree path,
which is forwarded directly to phosphor-hwmon.  The
phosphor-hwmon environment file is also templated, so
environment files must be placed in a devicetree
like-named directory tree under
/etc/defaults/obmc/hwmon/<dtreepath>.conf
