This was not tinderboxed. I'm getting build failures for powerpc and
sparc64. Please revert or fix.
Least of which: sys/dev/ofw/ofw_pci.c conflicts with
sys/powerpc/ofw/ofw_pci.c, which I mentioned in phabricator long ago.
Additionally, several files are missing includes of dev/ofw/ofw_bus_subr.h.
One example from tinderbox:
make[5]: "/scratch/tmp/jhibbits/obj/powerpc.powerpc/home/jhibbits/head/sys/GENERIC/Makefile"
line 7308: warning: duplicate script for target "ofw_pci.ln" ignored
