[PATCH v2 2/3] ARM: dts: sun8i: add usb_otg and OHCI/EHCI for usbc0 on H3

Allwinner H3 have a dual-routed USB PHY0 -- routed to either OHCI/EHCI
or MUSB controller.
Add device nodes for these controllers.

Changes in v2:
- Unbind PHY from *HCI controllers, as they do not know how to properly
handle the Vbus status.
