[PATCH v2] Fix CONFIG_PM_OPP without CONFIG_OF build failure

From: Rufus Hamade <rufus.hamade@imgtec.com>

A few `#ifdef CONFIG_OF` were missing, resulting in "unused function"
warnings in core.c.

I rebased on top of linux-next (30d0993ec9f6) from the repo
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
but there were no change (the patch is identical, save for the
removed change in cpu.c; not even a line number changed).
Which repo did you want me to rebase on?
