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.

+Subject: [PATCH] mtd: parsers: ofpart: support BCM4908 fixed partitions
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Some devices use fixed partitioning with some partitions requiring some
+extra logic. E.g. BCM4908 may have multiple firmware partitions but
+detecting currently used one requires checking bootloader parameters.
+
+To support such cases without duplicating a lot of code (without copying
+most of the ofpart.c code) support for post-parsing callback was added.
+
+BCM4908 support in ofpart can be enabled using config option and results
+in compiling & executing a specific callback. It simply reads offset of
+currently used firmware partition from the DT. Bootloader specifies it
+using the "brcm_blparms" property.
