Subject: [PATCH v3 0/5] Add JH7110 USB and USB PHY driver support

This patchset adds USB driver and USB PHY for the StarFive JH7110 SoC.
USB work mode is peripheral and using USB 2.0 PHY in VisionFive 2 board.
The patch has been tested on the VisionFive 2 board.

This patchset should be applied after the patchset [1], [2] and[3]:
[1] https://lore.kernel.org/all/20230221083323.302471-1-xingyu.wu@starfivetech.com/
[2] https://lore.kernel.org/all/20230215113249.47727-4-william.qiu@starfivetech.com/
[3] https://lore.kernel.org/all/20230223015952.201841-1-changhuang.liang@starfivetech.com/

This patchset is base on v6.3-rc1

patch 1 is usb phy and pcie PHY layer dt-binding document.
patch 2 is USB 2.0 PHY and PCIe PHY driver.
patch 3 is usb wrapper layer dt-binding document.
patch 4 is the wrapper module driver of Cadence USB3. USB controller IP is Cadence USB3.
patch 5 is USB device tree configuration.

changes
v3:
  1. Add patch 1 and patch2. Add USB driver. USB PHY codes are moved to patch 2.
  2. (patch 3) USB wrapper module dts document is moved to usb directory.
     Remove the 'dr_mode' and 'starfive,usb2-only' setting.
     Some dts format changes. dts binding check pass.
  3. (patch 4) Remove the PHY codes. 
     Search 'dr_mode' and phy setting from Cadence subnode.
  4. (patch 5) Add USB PHY dts configurion. 
     'dr_mode' is moved to Cadence controller submode.

v2:
