[PATCH v1] dt-bindings: usb: Fix EIC7700 USB reset's issue

[caohang]

From: Hang Cao <caohang@eswincomputing.com>

The EIC7700 USB controller requires a USB PHY RESET operation.PHY RESET
operation was missed in the verification version, as it was performed in
ESWIN's U-Boot.

If a non-ESWIN provided loader is used, this issue will occur, resulting
in USB not work.This patch does not introduce any backward incompatibility
since the dts is not upstream yet.

Fixes: c640a4239db5 ("dt-bindings: usb: Add ESWIN EIC7700 USB controller")
