dt-bindings: net: marvell,pp2: convert to json-schema
Convert the marvell,pp2 bindings from text to proper schema.
Move 'marvell,system-controller' and 'dma-coherent' properties from
port up to the controller node, to match what is actually done in DT.
Rename all subnodes to match "^(ethernet-)?port@[0-2]$" and deprecate
port-id in favour of 'reg'.
