Add thermal fault state sensor definition

Add a PDR definition for a new state sensor that is used to describe a
thermal fault.  This sensor has entity ID 91, cooling subsystem, and
uses the thermal trip state set, 21.

The D-Bus property behind it is provided by the phosphor-fan-monitor
application.  On IBM systems, this will be used to notify the host of
impending shutdowns due to fan faults.

At the current time, phosphor-fan-monitor only runs when system power is
on.
