[PATCH v6 0/1] riscv: dts: starfive: jh7110-milkv-mars: enable usb0 host function

Enable host mode JH7110 on-chip USB for Milk-V Mars by setting host mode
and connect vbus pinctrl.

This functionality depends on setting the USB over-current register to
disable at bootloader phase, for example U-Boot:

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). On Milk-V Mars with four USB-A ports this applies to one of the
USB-A ports and the remaining three VL805-connected USB-A ports via PCIe are
not changed.
