kernel: backport mtd implementation for "compatible" in "partitions" subnode
This backports upstream support for "compatible" DT property set for the
"partitions" subnode of flash node. It allows specifying how partitions
should be created/parsed. Right now only "fixed-partitions" is
supported.
It should eventually replace our downstream "linux,part-probe" solution.
