    arm64: dts: imx8-ss-dma: assign default clock rate for lpuarts
    
    [ Upstream commit ca50d7765587fe0a8351a6e8d9742cfd4811d925 ]
    
    Add the assigned-clocks and assigned-clock-rates properties for the
    LPUARTx nodes. Without these properties, the default clock rate
    used would be 0, which can cause the UART ports to fail when open.
