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://patchwork.kernel.org/project/linux-riscv/cover/20230314124404.117592-1-xingyu.wu@starfivetech.com/

[3] https://patchwork.kernel.org/project/linux-phy/cover/20230315100421.133428-1-changhuang.liang@starfivetech.com/

This patchset is base on v6.3-rc4

patch 1 is usb phy dt-binding document.
patch 2 is Pcie PHY dt-binding document.
patch 3 is USB 2.0 PHY driver.
patch 4 is PCIe PHY driver.
patch 5 is usb dt-binding document.
patch 6 is the wrapper module driver of Cadence USB3. USB controller IP is Cadence USB3.
patch 7 is USB device tree configuration.
