This is a port of Pantelis Antoniou's v3 port that makes use of the
new upstreamed configfs support for binary attributes.
Original commit message:
Add a runtime interface to using configfs for generic device tree overlay
usage. With it its possible to use device tree overlays without having
to use a per-platform overlay manager.
Please see Documentation/devicetree/configfs-overlays.txt for more info.
Changes since v2:
- Removed ifdef CONFIG_OF_OVERLAY (since for now it's required)
- Created a documentation entry
- Slight rewording in Kconfig
Changes since v1:
- of_resolve() -> of_resolve_phandles().

DT configfs: fix build error
There is an error when compiling rpi-4.6.y branch:
CC drivers/of/configfs.o
drivers/of/configfs.c:291:21: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
.default_groups = of_cfs_def_groups,
^
drivers/of/configfs.c:291:21: note: (near initialization for 'of_cfs_subsys.su_group.default_groups.next')
The .default_groups is linked list since commit
1ae1602de0.
This commit uses configfs_add_default_group to fix this problem.
