arm64: dts: rockchip: move usb dwc3 reset to core node for rk3399

Browse Source 
This patch moves the reset property of usb dwc3_0 and dwc3_1
to the dwc3 core node, then it can reset the dwc3 controller
in runtime PM and sleep PM, rather than only reset in sleep
PM. This can help to fix typec phy power on fail with the
following log when do hotplug test with Type-C dongle.

phy phy-ff7c0000.phy.9: phy poweron failed --> -110
