Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.

Add the check for the return value of kzalloc in order to avoid
NULL pointer dereference.

Provide NVMEM content to the NVRAM driver from a simple
memory resource. This is necessary to use NVRAM in a memory-
mapped flash device. Patch taken from OpenWrts development
tree.
This patch makes it possible to use memory-mapped NVRAM
on the D-Link DWL-8610AP and the D-Link DIR-890L.

Use kzalloc(...) rather than kcalloc(1, ...) because the number of
elements we are specifying in this case is 1, so kzalloc would
accomplish the same thing and we can simplify.

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.
