IB/core: Add get FW version string to the core
Allow for a common core function to get firmware version strings from the individual devices. In later patches this format can then then be used to pass a properly formated version string through the IPoIB layer. The problem with the current code in the IPoIB layer is that it is specific to certain hardware types. Furthermore, this gives us a common function through which the core can provide a common sysfs entry. Eventually we may want to remove the sysfs export but this provides for user space backwards compatibility.
