[PATCH 02/16] nvmem: brcm_nvram: find Device Tree nodes for NVMEM cells

[Srinivas Kandagatla]

From: Rafał Miłecki <rafal@xxxxxxxxxx>

DT binding for Broadcom's NVRAM supports specifying NVMEM cells as NVMEM
device (provider) subnodes. Look for such subnodes when collecing NVMEM
cells. This allows NVMEM consumers to use NVRAM variables.
