Subject: [PATCH v3 0/3] Add devicetree support of USB for QDU/QRU1000

This series adds devicetree nodes to support interconnects and usb for qdu/qru1000.
This is based on previously sent driver series[1].

------
Changes in v3:
* As per comments on upstream[2], to get role-switch working on QDU/QRU1000, it was recommended to
  use the actual TI switch driver. Since driver doesn't have the functionality to provide role-switch
  based on gpio, thus reverting back USB dr_mode to peripheral and removed the remote end-point nodes
  and usb-conn-gpio based role switch functionality.
* Link to v2: https://lore.kernel.org/linux-arm-msm/20240319091020.15137-1-quic_kbajaj@quicinc.com/

Changes in v2:
* Changes qmpphy node name
* Changes dr_mode to otg and added USB-B port USB role switch
* Dropped maximum-speed property from usb dwc3 node
* Link to v1: https://lore.kernel.org/linux-arm-msm/20240311120859.18489-1-quic_kbajaj@quicinc.com/
