[PATCH v3 00/17] Improve MTD bindings

[Miquel Raynal <miquel.raynal@bootlin.com>]

Hello,

During a yaml conversion review, Krzysztof opened the discussion about
the links and references made between the different files in the mtd
bindings. I figured out some minimal changes might be needed to properly
reference everything correctly and ensure we constrain as much as
possible the existing bindings. That is what I tried to do here.

The idea is:
* partition.yaml defines one MTD partition
* parsers/*.yaml define partition parsers (mainly compatibles)
* mtd.yaml contains the generic definition of any mtd device (nand,
  spi-nand, spi-nor, nor, sram, etc), in particular, it defines the
  various partition formats (legacy and current) and references
  partition.yaml as well as a list of all the possible parsers within a
  "partitions" node.
* nand-chip.yaml, jedec,spi-nor, mtd-physmap.yaml all describe real
  instances of mtd device, each of them with a different underlying
  technology, they reference mtd.yaml 
* nand-controller.yaml has subnodes which reference nand-chip.yaml.
* Specific NAND controller bindings reference nand-controller.yaml.

I've tested each and every patch with the following command and it
worked fine:
$ make dt_binding_check -j10 DT_CHECKER_FLAG=-m DT_SCHEMA_FILES=mtd/

Cheers,
Miquèl

Changes since v2:
* Added Rob's R-by on almost all the patches but
  "dt-bindings: mtd: nvmem-cells: Fix example"
* Changed the commit message of the patch mentioned above to mention
  that 'ranges' is not declared anywhere besides being a potentially
  valid property, hence dropping it from the example just to avoid
  failing the test, knowing that at some point someone could reintroduce
  it by defining it in one of the core yaml files.
