Add USB phy and controller nodes.

Signed-off-by: Varadarajan Narayanan <quic_varada@quicinc.com>

v4:
	Change node name
	Remove blank line
	'make CHECK_DTBS=y DT_SCHEMA_FILES=qcom qcom/ipq5332-rdp441.dtb' passed
v1:
	Rename phy node
	Change compatible from m31,ipq5332-usb-hsphy -> qcom,ipq5332-usb-hsphy
	Remove 'qscratch' from phy node
	Fix alignment and upper-case hex no.s
	Add clock definition for the phy
	Remove snps,ref-clock-period-ns as it is not used. dwc3_ref_clk_period()
	in dwc3/core.c takes the frequency from ref clock and calculates fladj
	as appropriate.

DT_SCHEMA_FILES accepts yaml files

I followed the example given in https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/

		make CHECK_DTBS=y DT_SCHEMA_FILES=trivial-devices.yaml qcom/sm8450-hdk.dtb
		make CHECK_DTBS=y DT_SCHEMA_FILES=/gpio/ qcom/sm8450-hdk.dtb
	---->	make CHECK_DTBS=y DT_SCHEMA_FILES=qcom qcom/sm8450-hdk.dtb

Will include the yaml from next time.

Thanks
