Log:
Allow bus barrier operations on fake tags. The purpose of a fake
bus tag is to allow bus space accesses prior to having newbus
fully initialized, such as would be the case for console drivers.
Since barriers are a fundamental part of bus space accesses, not
allowing them on fake tags would defeat the purpose of these tags.
We use the barrier function normally associated with nexus. This
is the barrier used when subordinates haven't defined a barrier
themselves.
