Yeah, diffs are not actually readable, so looks like we have to do this
piece-wise. One thing that really bugs me is that we have all these
per-chip function declared as extern now, and the setup code for them is
somewhere completely different.

So can you add another patch add the end that moves all that setup code
intel intel_init_pm (at the end of intel_pm.c to avoid forward decl) and
removes all these chip-specific extern declarations?

If that patch doesn't result in only a few generic functinos exported from
intel_pm.c (and hence a simple interface) I think we need to reconsider
whether we've moved the right things in there (maybe it needs more/less).
But I can't easily judge that atm.
Yours, Daniel
