[0/3] i915: General multicast steering updates

Message

A few minor steering updates, mostly to prepare for other upcoming work.
We'll soon be doing most of our steering explicitly, rather than relying
on implicit steering as we do now, so reporting the steering assignments
in debugfs will be helpful for debugging.  We also have some features
coming up soon that need to be able to issue unicast writes to a
specific register instance.  Finally, we need to inform the GuC about
proper register steering so that it knows how to handle register
save/restore operations.
