From: Michal Suchanek <hramrach-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

The lock flag of ofpart is undocumented. Add to binding doc.

It seems my reasoning here [1] was wrong (thanks Sascha!). This is a rewrite of
Michal's binding doc from [2].

Note that this property is still broken for the CONFIG_MTD_PARTITIONED_MASTER=y
case.
