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.

commit d8764d347bd737efec00fae81133ffad0ae084bb (tag: zynqmp-dt-for-6.9)

     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.
