Subject[PATCH v3 1/3] dt-bindings: phy: add assign clock property in usb2-phy node
On some platform such as RK3328, the 480m clock may need to assign
clock parent in dts in stead of clock driver. So this patch add
property of assigned-clocks and assigned-clock-parents to assign
parent for 480m clock.

Changes in v2:
- move usb2-phy grf specification to grf.txt
Changes in v3: None
