Unfortunately, after some more testing, this needs a follow-on fix,
included below and also committed to SILO git.
Sorry for the confusion.
====================
silo: Don't assume P1275 OBP means sun4u.
It could also mean 'sun4v'.
Code this defensively, so that if (for whatever reason)
we can't get at the 'compatible' property in the root
OBP device node we'll still default to sun4u as previous.
