sky2: Add module parameter for passing the MAC address
For designs where EEPROMs are not connected to PCI Yukon2
chips we need to get the MAC address from the firmware.
Add a module parameter called 'mac_address' for this. It
will be used if no DT node can be found and the B2_MAC
register holds an invalid value.
