linux-next: manual merge of the devicetree tree with the pm, mfd and regulator trees

Hi Grant,

Today's linux-next merge of the devicetree tree got a conflict in
include/linux/of.h between commits b31384fa5de3 ("Driver core: Unified
device properties interface for platform firmware") from the pm tree
and a4b4e0461ec5 ("of: Add standard property for poweroff capability")
from the mfd and regulator trees and commit 7518b5890d8a ("of/overlay:
Introduce DT overlay support") from the devicetree tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

This patch actually originated from the Regulator tree.  I pulled it in
to avoid conflicts between MFD and Regulator.  I guess OF needs to do
the same to avoid a conflict when Linus pulls them in.
