arm64: dts: ti: k3-j784s4-main: Add WIZ and SERDES PHY nodes
Browse files Browse the repository at this point in the history 
J784S4 SoC has 4 Serdes instances along with their respective WIZ
instances. Add device-tree nodes for them and disable them by default
as the node is incomplete and phy link properties will be added in
the platform dt file.
