[PATCH 04/18] dt-bindings: mtd: spi-nand: Convert spi-nand description file to yaml

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

Let's get rid of spi-nand.txt by converting it to yaml schema. While at
converting this file, let's actually pull all the generic properties
from nand-chip.yaml which might apply to a SPI-NAND chip.
