arm64: dts: rockchip: dis u1 and u2 state for rk3568 dwc3 device

Browse Source 
According the commit 729dcffd1e ("usb: dwc3: gadget: Add
support for disabling U1 and U2 entries"), it's necessary
to disable the U1 and U2 low power state to improve USB 3.0
performance for mass storage gadget and uvc gadget.

In addition, it can help to avoid the dwc3 wakeup failed
from U1 or U2 state when connect to the Host USB 3.0 interface.
