[PATCH RFC] dt-bindings: mtd: allow NVMEM cells in BCM4908 partitions

["Rafał Miłecki" <zajec5@gmail.com>]

From: Rafał Miłecki <rafal@milecki.pl>

Every MTD partition can be NVMEM provider now. It's not handled by the
shared partition.yaml so add proper "compatible" to the BCM4908.

Ideally I'd like to have:
1. partition.yaml allowing "nvmem-cells" by using nvmem-cells.yaml
2. brcm,bcm4908-partitions.yaml using partition.yaml and extending the
   compatible list by "brcm,bcm4908-firmware"

I don't know if such a solution is possible to implement using YAML?

Proposed solution (RFC) isn't a really clean one:
1. It duplicates "nvmem-cells" which is already in the nvmem-cells.yaml
2. Generic "nvmem-cells" should be part of the partition.yaml

Rob? Help? :)
