dt-bindings: phy: add binding document for Allwinner F1C100s USB PHY 



Allwinner F1C100s has the most simple USB PHY among all Allwinner SoCs,
because it has only one OTG USB controller, no host-only OHCI/EHCI
controllers.

Add a binding document for it. Following the current situation of one
YAML file per SoC, this one is based on
allwinner,sun8i-v3s-usb-phy.yaml, but with OHCI/EHCI-related bits
removed. (The same driver in Linux, phy-sun4i-usb, covers all these
binding files now.)
