pmap_page_index() is used only in vm_page_bootstrap() in
vm_page.c, but all of them are in #elif defined(MACHINE_NONCONTIG).
`nm /sys/arch/sun3/compile/GENERIC3X/*.o` shows no reference to
pmap_page_index(). Of course, UVM is not defined in GENERIC3X.

Now all ports switch to MACHINE_NEW_NONCONTIG, so we can purge
all old NONCONTIG codes. I'm not sure which functions are used only
by old NONCONTIG, though..
