Add Accessible Max Address Configuration support to camcontrol.

Description

Add Accessible Max Address Configuration support to camcontrol.

AMA replaced HPA in ACS-3 specification. It allows to limit size of the
disk alike to HPA, but declares inaccessible data as indeterminate. One
of its practical use cases is to under-provision SATA SSDs for better
reliability and performance.

While there, fix HPA Security detection/reporting.
