mtd: abstract last MTD partition parser argument
Encapsulate last MTD partition parser argument into a separate structure. Currently it holds only 'origin' field for RedBoot parser, but will be extended in future to contain at least device_node for OF devices. Amended commentary to make kerneldoc happy Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Artem Bityutskiy <dedekind1@gmail.com>
