dt-bindings: net: Document Marvell PHY "marvell,reg-init"

Browse source

The Marvell PHY driver consumes marvell,reg-init as one or more
<page register mask value> tuples. Define the property so dtbs_check
validates the existing board descriptions.

Existing users have no compatible or just "ethernet-phy-ieee802.3-c22"
so this has to go into the generic ethernet-phy.yaml schema. Marking it
deprecated both for that reason and because opaque register
initialization values are discouraged in DT.
