Hello,

Now that we are aligned on how to make information available from static
storage media to drivers like Ethernet controller drivers or switch
drivers by using nvmem cells and going through the whole nvmem
infrastructure, here are two driver updates to reflect these changes.

Prior to the driver updates, I propose:
* Reverting binding changes which should have never been accepted like
  that.
* A conversion of the (old) Prestera and DFX server bindings (optional,
  can be dropped if not considered necessary).
* A better description of the more recent Prestera PCI switch.

Please mind that this series cannot break anything since retrieving the
MAC address Prestera driver has never worked upstream, because the (ONIE
tlv) driver supposed to export the MAC address has not been accepted in
its original form and has been updated to the nvmem-layout
infrastructure (bindings have been merged, the code remains to be
applied).

Thanks,
Miquèl

Changes in v2:
* Bindings:
  - Add Rob's tags.
  - Use "additionalProperties: \n type: object" in both yaml files.
  - Add missing PCI properties to the prestera example as suggested.
  - Added a limitation over the number of register entries in the
    dfx-server description.
* Drivers:
  - Export the of_ helper retrieving MAC addresses from nvmem cells.
  - Add a comment in mvpp2 to say that the nvmem lookup only is valid on
    OF enabled platforms as suggested by Marcin.
