mxser rework to allow dynamic structs
This patch is preparing for further patches (probing) to allow allocated
structures to behave as private data in probe structures.
Union two different structures used in the driver (hw_conf and port/board
descriptor) to another 2: port and board not to initialize 2 different
things and to have ports contained in board.
