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.
