kernel: add the latest mtd patch extending ofpart parser

This adds the latest version of ofpart commit. It hopefully
1. Doesn't break compilation
2. Doesn't break partitioning
(this time).

It's required to implement fixed partitioning with some quirks. It's
required by bcm53xx, bcm4908, kirkwood, lantiq and mvebu.
