sparc64 ramdisks do not include mfi(4) or mfii(4).

In fact, sparc64 currently does not build/use either of those drivers.
GENERIC.MP builds and boots fine with both enabled, but I have no
hardware to run-test these drivers.
Can anyone test this on real hardware or do we want to just enable it
for users to pick up?
If that works for Michael, I can build and boot-test RAMDISK later on.
