6.7-stable review patch. If anyone has any objections, please let me know.

From: Mantas Pucka <mantas@xxxxxxxxxxxx>
[ Upstream commit 62a5df451ab911421da96655fcc4d1e269ff6e2f ]
Commit 23fd679249df ("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.
