Add USB phy and controller related nodes

Signed-off-by: Varadarajan Narayanan <quic_varada@quicinc.com>
---
 Changes in v3:
	- Insert the nodes at proper location

 Changes in v2:
	- Fixed issues flagged by Krzysztof
	- Fix issues reported by make dtbs_check
	- Remove NOC related clocks (to be added with proper
	  interconnect support)
