[PATCH 12/13] phy: qcom-qmp-usb: restructure PHY creation

Johan Hovold
2022-10-24T10:08:03Z

In preparation for supporting devicetree bindings which do not use a
child node, move the PHY creation to probe() proper and parse the serdes
and dp_com resources in what is now the legacy devicetree helper.
