qlge: Add support for varied pcie function numbers.
Currently we support only PCIe NIC functions zero and one, and FCoE functions as 3 and 4. Future configurations can mix these up in any fashion. This patch removes the 0-1 dependancy and allows usage of any of the 4 functions. We also find the alternate NIC function (if exist) and determine our port number based on the comparison of the two functions: Lower function number gets first port, higher function gets second port.
