Revert "phy: qcom-qusb2: add QUSB2 support for IPQ5424"
[ Upstream commit 8a040e13afd94a1f91acaf8e0505769d4f7f5af4 ]
With the current settings, compliance tests especially eye diagram
(Host High-speed Signal Quality) tests are failing. Reuse the IPQ6018
settings to overcome this issue, as mentioned in the Hardware Design
Document.
So revert the change which introduced the new settings and reuse the
IPQ6018 settings in the subsequent patch.
