Subject: [RESEND PATCH] dt-bindings: nvmem: Use soc-nvmem node name instead of nvmem

Based on commit d8764d347bd7 ("dt-bindings: firmware: xilinx: Describe
soc-nvmem subnode") soc-nvmem should be used instead of simple nvmem that's
why also update example to have it described correctly everywhere.

Rob:
 This doesn't seem like an improvement. Is there another nvmem node at
 this level? I would fix the binding instead if not.

Michal:
That name came from discussion with Conor. None suggested to fix dt-schema that's why soc-nvmem has been propagated to DT already and this patch is just fixing last occurrence.

    dt-bindings: firmware: xilinx: Describe soc-nvmem subnode

    Describe soc-nvmem subnode as the part of firmware node. The name can't be
    pure nvmem because dt-schema already defines it as array property that's
    why different name should be used.
