New property to clear or reset the security keys

Defining a new property which can be used as a bit mask to indicate
clearing certain security keys or resetting those values back to its
default from the system by the host. This will be mapped to a new IPMI
sensor. Setting this property does not guarantee a successful operation
as additional conditions like the physical presence pin or jumper
settings will be checked by the host to clear/reset the sensitive data.

Some of customer use cases include clearing OS platform key, clearing
system security officer certificate and resetting the system key value
back to its default state.

An external user should be able to update the value using ipmitool.
