dt-bindings: mtd: convert IBM NDFC binding to YAML

The NDFC NAND flash controller was only described in a legacy text file,
so dtbs_check reported "failed to match any schema with compatible:
['ibm,ndfc']" for the ndfc nodes of the bluestone, canyonlands, eiger,
glacier, sequoia and warp device trees.

Convert the binding to the YAML format so those nodes match the generic
nand-controller-legacy schema.  Describe the node's reg, ccr and
bank-settings properties, along with its "nand" chip node which carries
the legacy partition layout.

The "nand" chip node carries no unit address, so the "nand@[a-f0-9]"
pattern of nand-controller-legacy.yaml never matches it and
raw-nand-chip.yaml is never applied.  Describe it with mtd.yaml,
nand-property.yaml and raw-nand-property.yaml instead, the way the
controller level does, so that both the deprecated partition@ nodes and
a modern "partitions" subnode are accepted.  The node name does not
matter, the driver picks the first child of the controller node.
