* add overlay to force RK3399 DW3 USB-C port to host mode
* Per https://forum.armbian.com/topic/13721-nanopc-t4-usb-type-c-port-doesnt-work-with-buster-current-5431/
this is for the NanoPC-T4 as the default from the Device Tree is to set port 0 (USB-C port) to OTG mode,
and the current kernel fusb302 driver is unable to perform autonegotiation to switch the port to host
mode when required.
* As a result, and since most users will want to use this port in host mode, Armbian should provide a new
overlay to do just that.
* rename overlay to a more generic "dwc3-0-host"
