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:
https://patchwork.ozlabs.org/project/uboot/patch/20241012031328.4268-6-minda.chen@starfivetech.com/

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.

Changes since v3:

 - use tabs for code indent
