4eda414b09 kernel: mtd: backport extended dynamic partitions support

1a9ee36734 kernel: backport mtd dynamic partition patch
Backport upstream solution that permits to declare nvmem cells with
dynamic partition defined by special parser.

This provide an OF node for NVMEM and connect it to the defined dynamic
partition.

generic: sync mtd rootfs hack with part_bits
In commit ab143647ef ("kernel: generic: improve FIT partition parser")
part_bits was bumped to 2 in order to allow up to 3 additional FIT
sub-images mapped into sub-partitions.
This change has to be reflected also in our local patch
420-mtd-set-rootfs-to-be-root-dev.patch
which still assumed part_bits==1 for mtdblock devices in case of
CONFIG_FIT_PARTITION=y.
