        syssrc/sys/dev/pci: pci.c

Log Message:
Fix the semantics of __PCI_DEV_FUNCORDER so that they're actually useful:
If __PCI_DEV_FUNCORDER is defined, don't do the song-and-dance to check if
a device is multi-function; machdep code is going to tell us exactly which
functions to probe.

Note this required changing how pci_func_devorder() works in the
sparc64 PCI machdep code; now the "curnode" is assumed to point
to the bus, rather than some function (typically 0) on the device,
just as pci_bus_devorder() makes that assumption.

All this should allow the PCI code to actually locate the second
HME device on a Sun Netra t1, which is at 3,1 -- previously, the
PCI code would have missed it because there is no device at 3,0.

(Sun deserves a brick to the head for this one -- this seems clearly
out of line with the PCI spec.)
