This is a new & warm feature that allows nesting partiitons in DT and
mixing their types (e.g. static vs. dynamic). It's very useful for
boards that have most partitions static but some of them require extra
parsing (e.g. a "firmware" partition).
It's required to successfully backport support for new devices using
that new syntax in their DT files.
Since brcm63xx has a custom alternative patch the upstream one is being
reverted for it. The plan is to make brcm63xx use the upstream
implementation.

In the commit bde5e7a632 ("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.
