[PATCH 0/9] Flatten USB Controller Nodes on IPQ SoCs

[George Moussalem via B4 Relay]

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

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.

I've split these patches from a larger patch set to add USB3 support on
IPQ5018 and IPQ5332 SoCs where these patches are required to ensure new
functionality is added to the new flattened driver and binding model.
