Posted this as a small set now, with an (optional) second patch that shows
how the changes work and what I've used to test the code on a Topic Miami board.

v3: Add patch that implements mac in nvmem for the Cadence MACB controller
    Remove the integrated of_get_mac_address call

v2: Use of_nvmem_cell_get to avoid needing the assiciated device
    Use void* instead of char*
    Add devicetree binding doc

Mike Looijmans (2):
  of_net: Implement of_get_nvmem_mac_address helper
  net: macb: Try to retrieve MAC addess from nvmem provider
