Minor MIPS tree pruning

[Warner Losh]

I might have a board the sibyte port would work on, but it's buried in a
pile of ewaste and would take me days of time to even try to see if it
works. I didn't delete the sibyte when I pulled the trigger last week
because the platform can support at least 128MB of RAM. But it's in the
cross hairs for someone to prove it works or it will be GC'd at some
unspecified point in the future.

I'm thinking of adding this near the end of mips_init in sb_machdep.c:

printf("This platform is believed broken and will be removed before FreeBSD
12.\n");
printf("Email mips at freebsd.org if you have it working.\n");
