[phantom] Assume one net device per PCI function 

The Phantom firmware selectively disables PCI functions based on the
board type, with the end result that we see one PCI function for each
network port.  This allows us to eliminate the code for reading from
flash and, more importantly, removes knowledge of the board type magic
number from the gPXE driver.
