[PATCH 4/9] arm64: dts: qcom: ipq5018: Flatten usb controller node

[George Moussalem via B4 Relay]

From: George Moussalem <george.moussalem@xxxxxxxxxxx>

Flatten usb controller node and update to using latest bindings and
flattened driver approach.

Add property to select UTMI as reference clock for the DWC3 core to
calculate the right values for the period and frame length adjustment.

In addition, set the right UTMI clock rate and override any clock
rate inherited from the bootloader.
