[PATCH v3 03/10] arm64: dts: qcom: ipq5018: Flatten usb controller node

[George Moussalem via B4 Relay <devnull+george.moussalem.outlook.com@kernel.org>]

From: George Moussalem <george.moussalem@outlook.com>

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

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