Add Starfive JH7110 Cadence USB driver and related PHY driver. So the codes can be used in visionfive2 and star64 7110 board.
The driver is almost the same with kernel driver.
Test with Star64 JH7110 board USB 3.0 + USB 2.0 host. The code can work.
The Starfive JH7110 has enable CONFIG_OF_UPSTREAM. The dts is from kernel

- patch description.
patch1: Add set phy mode function in cdns3 core driver which is used by Starfive JH7110. patch2-3: USB and PCIe 2.0 (usb 3.0) PHY drivier patch4: Cadence USB wrapper driver. patch5: Get the dr mode from wrapper device node. patch6: Add JH7110 USB default overcurrent pin. patch7: config update. patch8: MAINTAINERS update
- change: v6: - patch 5 format changed. - split v5 patch4 to v6 patch 4 and patch 5 - delete v6 dts patch7 because the StarFive JH7110 CONFIG_OF_UPSTREAM is enbled. v5: - patch 2-4 format changed. - For pareparing enable OF_UPSTREAM, patch4 get the dr mode from parent device dts node not the cdns core device dts. - patch2 add a common usb syscon setting headfile. - delete v4 patch8 and the star64 dts setting can be setting int star64 board dts configuration if the OF_UPSTREAM is enable. v4: - patch 2 Add usb split setting, default set USB 2.0 only. - patch 5 move to spl stage. - Add a new patch 8 for star64 board usb host, vbus pin setting and usb 3.0 v3: - patch 1 Move the added code to cdns3_drd_update_mode(). - patch 1-4 correct the code format.(follow Rogers's comments.) - patch 3 using regmap_field.
v2: - patch 1 Move the added code to cdns3_core_init_role(). Must set PHY mode before calling cdns3 role start function. - patch 1-4 correct the code format.(follow Marek's comments.) - patch 2 Add set 125M clock in PHY init function. - Add new patch5.
