[PATCH 3/5] phy: qcom: qmp-usb: Add IPQ9650 USB3 PHY configuration

[Varadarajan Narayanan <varadarajan.narayanan@oss.qualcomm.com>]

Add the USB3 QMP PHY configuration for IPQ9650, including the SoC-specific
init tables and compatible data.

IPQ9650 uses settings that do not match any existing supported SoC, so add
a dedicated configuration to allow the driver to support it.
