phy: qcom-qmp-usb: fix serdes init sequence for IPQ6018

Commit 23fd6792 ("phy: qcom-qmp: add USB3 PHY support for IPQ6018")
noted that IPQ6018 init is identical to IPQ8074. Yet downstream uses
separate serdes init sequence for IPQ6018. Since already existing IPQ9574
serdes init sequence is identical, just reuse it and fix failing USB3 mode
in IPQ6018.
