Series phy: qcom-qmp-ufs: fix sc8280xp binding | expand

Commit Message

Johan Hovold Oct. 24, 2022, 9 a.m. UTC 
In preparation for supporting devicetree bindings which do not use a
child node, move the PHY creation to probe() proper and parse the serdes
resource in what is now the legacy devicetree helper.
