Changesets are very powerful, but the lack of a helper API
makes using them cumbersome. Introduce a simple copy based
API that makes things considerably easier.

To wit, adding a property using the raw API.

	struct property *prop;
	prop = kzalloc(sizeof(*prop)), GFP_KERNEL);
	prop->name = kstrdup("compatible");
	prop->value = kstrdup("foo,bar");
	prop->length = strlen(prop->value) + 1;
	of_changeset_add_property(ocs, np, prop);

while using the helper API

	of_changeset_add_property_string(ocs, np, "compatible",
			"foo,bar");

Changes in v2 (hdegoede-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org):
-Address review comments from:
 https://www.spinics.net/lists/kernel/msg2252845.html

That points to the May 9 version 1 patches from Pantelis (as expected),
but containing 4, not 2, patches.  Patch 1/4 was applied.  Patch 4/4
seems to have disappeared?

Pantelis then sent a version 2 set of the patches on May 16.

Your version is a modification of the May 9 patches (as would be expected
of a version 2).  It is confusing to have two different version 2 patch
sets.  I don't have any brilliant ideas on how this patch set could have
been named differently to avoid that confusion.

The point of this little side-track is simply to note the existence of two
different version 2 series so I won't be confused when I revisit this
thread in the future.

 -Simplify (and fix) __of_changeset_add_update_property_copy OOM handling
 -Remove (by manual inlining) these 2 static helpers:
  __of_changeset_add_update_property_u32
  __of_changeset_add_update_property_bool
 -Remove the following exported helper method:
  of_changeset_node_move_to

Not all comments were addressed.

There are some other changes made that are not noted in the changelog.

I am still reading through the patches. I will reply again either with
a reviewed-by or specific comments when I finish.

-Frank
