arm64: dts: qcom: ipq5018: Add clocks required for USB3 support

This commit adds the auxiliary and LFPS clocks to the USB controller node
in the IPQ5018 device tree to enable Super-Speed (USB3) mode. It also sets
default assigned clocks and clock rates for the controller.

[Severity: Medium]
The commit message mentions adding the aux and lfps clocks for USB3 support,
but does not document adding these assigned-clocks and assigned-clock-rates.

Could the commit message be updated to explain the rationale for forcing these
specific 200MHz and 60MHz frequencies during initialization?
