Ok

It's what I intended to do, but there were two problems with that:
- of_get_mac_address() returns a pointer to constant data in memory, but the
nvmem functions return an allocated memory object that must be freed after
use. This changes the way the call is to be made.
- The nvmem functions need the "struct device" pointer as well, while
of_get_mac_address() only gets passed the DT node.

Does of_nvmem_cell_get() help?

Yes, looking at the interface, it would.
