Enable host mode JH7110 on-chip USB for Milk-V Mars by setting host mode and connect vbus pinctrl. This functionality depends on: 1. commit e10c52e7e064038d9bd67b20bf4ce92077d7d84e "phy: starfive: jh7110-usb: Fix link configuration to controller" 2. Setting the USB over-current register to disable. This is done at bootloader phase, for example U-Boot: https://patchwork.ozlabs.org/project/uboot/patch/20241012031328.4268-6-minda.chen@xxxxxxxxxxxxxxxx/ If the over-current register is not prepared for us then the result is no change in functional outcome with this patch applied; there is an error visible to the user and this additional usb configuration fails (same as it is now). The existing three VL805 connected USB ports via PCIe on Milk-V Mars are not affected.
