arm64: dts: Add more serial port nodes in APM X-Gene device treev3.14/topic/arm64-apm
APM X-Gene Storm SoC supports 4 serial ports. This patch adds device nodes for serial ports 1 to 3 (a device node for serial port 0 is already present in the dts file). This patch also sets the compatible property of serial nodes to "ns16550a".
