arm64: dts: rockchip: rk3588: Disable u1 and u2 state for USB OTG1 device

Browse Source 
The USB3.0 OTG1 interface support Dual-Role Device (DRD)
features, it means that supports either device or host
operation separately, not simultaneously. In most application
scenarios, the OTG1 is used as host mode. But there are
some scenarios that need two USB devices at the same time
on the RK3588 platform, in this case, it needs to set both
the OTG0 and OTG1 in device mode. In order to improve the
OTG1 USB3.0 device performance and stability, this patch
disable the u1 and u2 state for OTG1, like what the OTG0
has done.
