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.

Changes in v2: - Fix typo in subject - Make example bigger requested by Conor
Dt binding for nvmem node has been already merged and it is the part of linux-next tree. Here is the reference to it just in case: https://lore.kernel.org/r/170635581622.41421.8980881999042944764.b4-ty@linaro.org
