This commits enables the basic infrastructure to add service
actions(guard/deconfigure) supports for "phal"  feature enabled
systems. Also enabled "guard" related service , which includes
creating guard D-Bus object using hardware isolation D-Bus api's

To enable this support, PEL users has to include the array of
JSON callouts, which includes the below required informations.
"EntityPath": entity path of the hardware from the PHAL device tree.
"GuardType":  Guard type string defined libekb_p10.
"Guarded": boolean, true to create guard records.

Tested: created guard records and verified
