[PATCH v4 0/1] riscv: dts: starfive: jh7110-pine64-star64: enable usb0 host function

Enable host mode JH7110 on-chip USB for Pine64 Star64 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 usb configuration fails (same as it is now).

Changes since v3:
 - Rebase on latest master
 - Addtional detail to commit description

Changes since v2:
 - Rebase on latest master

Changes since v1:
 - Rebase on linux-next/master
 - use tabs for code indent
