dt-bindings: Remove 'Device Tree Bindings' from end of title:

As indicated in
link: https://lore.kernel.org/all/20220822204945.GA808626-robh@kernel.org/

DT schema files should not have 'Device Tree Binding' as part of there

converting this file, let's actually pull all the generic properties
from nand-chip.yaml which might apply to a SPI-NAND chip.
