[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.
