Since composible cache may be L3 cache if private L2 cache exists, it

Looks like Rob's bot had comments and I don't see a v2. Sorry if I'm
missing something.
Also: I'd guess that we only had the SOC-specific mappings on purpose.
It's kind of a grey area and I'm OK either way, but I'd definately
prefer the DT folks to get a chance to review these. My guess is that
they're not looking due to the bot comments, but sorry again if I've
missed it.
