The uart1 node was missing the 'clock-frequency' property. This meant the driver for this device would fail at probe. The clock for uart1 is fed from the same source as uart0 and is a fixed 200MHz clock. This is confirmed via documentation for the CN9130 SoC and from the equivalent code in Linux at: <linux>/arch/arm64/boot/dts/marvell/armada-ap80x.dtsi where uart0 and uart1 share a common 'clocks' definition.
