PEL: Update pel_values to support bmcweb

Updates done to support display of Message property in bmcweb.
With the redfish command the message property showed up as
--old-
"Message": "xyz.openbmc_project.Power.PowerSupply.Error.InputFault"
--New--
"Message": "110015F0 event in subsystem: Power Supply",

Note that the "Power Supply" is a $subsystem property and had ':' in the
description, to enhance readability the $subsystem for CEC Hardware is
update with '-' in place of ':'.
