Up till now only single character ('A' or 'B') was used to provide
information of HSR slave network device status.

As it is also possible and valid, that Interlink network device may
be supported as well, the description must be more verbose. As a result
the full string description is now used.

Changes for v2:
- Use const char * instead of char * - to assure that pointed string is
  immutable (.rodata allocated).
