location code: add new item interface to support more connections types

Provide informaiton on different types of physical connections.
Supporting:
 - Slot
 - Embedded

Only supporting these two options since it can be used to cover most
cases.

The location type can be used by the IPMI OEM or Redfish to represent
the physical location of the hardware. A client wrapper client around
IPMI/Redfish can use it along with physical location to determine/build
device path of the hardware.
