[PATCH] Char: 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.
