arm64: dts: rockchip: Add pcie1 slot for rk3576 evb1 board
PCIe1 and usb_drd1_dwc3 is sharing the same PHY on RK3576 platform.
For pcie1 slot and USB interface, there is a swich IC labelled as
Dial_Switch_1 on evb1 board. If we need to make pcie1 slot work for this
board, we should first disable usb_drd1_dwc3 and then set Dial_Switch_1
to low state.
