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
ports and the remaining three VL805-connected ports via PCIe are not changed.
Changes since v4:
- Rebase on latest master
Changes since v3:
- Rebase on linux-next/master
- use tabs for code indent
Changes since v2:
- Rebase on 6.12
