A property map holds the collection of the properties for a given device identifier. HAL modules allocate and release these property maps to control the lifetime of the data. The host will typically open and read the corresponding idc file on allocation, and release these resources when it is freed. Change-Id: Ia13ec7b7abf1a79eeed87dc744c174a37f1fb8a9
