 FWIW, it's not unusual even if not common for multifunction devices to 
have "holes" in functions, e.g.:

07:00.0 Parallel controller [0701]: Oxford Semiconductor Ltd OXPCIe952 Parallel Port [1415:c118]
07:00.3 Serial controller [0700]: Oxford Semiconductor Ltd OXPCIe952 Native 950 UART [1415:c11b]

which is a chip the functions of which (one or two native or legacy serial 
ports, one parallel port, one GPIO interface) can be activated selectively 
with reset straps, however the resulting numeric 0-3 function assignments 
for individual interfaces are not necessarily contiguous, presumably to 
simplify internal decoding logic.
