v3:
	Incorporate review comments. Will bring in ipq5018 compatible
	string while posting ipq5018 usb patchset.

v1:
	Rename qcom,m31.yaml -> qcom,ipq5332-usb-hsphy.yaml
	Drop default binding "m31,usb-hsphy"
	Add clock
	Remove 'oneOf' from compatible
	Remove 'qscratch' region from register space as it is not needed
	Remove reset-names
	Fix the example definition
