kernel: use V10 of mtd patchset adding support for "compatible" string

In the commit bde5e7a632ef0 ("kernel: backport mtd implementation for
"compatible" in "partitions" subnode") patches that got accepted into
l2-mtd.git were backported to the kernels 4.9 and 4.14. Unfortunately
there was a regression report, patches were dropped and never reached
4.16.

This commit replaces these pseudo-backports with the latest version
that includes regression fix and futher changes that were requested.

-From: Hauke Mehrtens <hauke@hauke-m.de>
-Subject: mtd: part: add generic parsing of linux,part-probe
-
-This moves the linux,part-probe device tree parsing code from
-physmap_of.c to mtdpart.c. Now all drivers can use this feature by just
-providing a reference to their device tree node in struct
-mtd_part_parser_data.
