Subject: [PATCH v5 4/6] arm64: dts: qcom: ipq5332: Add USB related nodes

Add USB phy and controller nodes.

Signed-off-by: Varadarajan Narayanan <quic_varada@...cinc.com>
---
v5:
	Use generic phy instead of usb-phy
	'make CHECK_DTBS=y DT_SCHEMA_FILES=qcom dtbs_check' passed
	'DT_CHECKER_FLAGS='-v -m' DT_SCHEMA_FILES=qcom dt_binding_check' passed
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.
