mxser_new, rework to allow dynamic structs
This patch is preparation for further patches (pci probing) to allow
allocated structures to be private data in pci_dev structure.
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 structure.
