[PATCH 2/3] arm64: dts: apq8016-sbc: add label properties for UART, I2C, and SPI

[robh@kernel.org (Rob Herring)]

Add label properties to provide a way to identify UART, I2C and SPI
ports based on their connector names. This follows naming convention in
96boards CE spec. Ports without external connections are not labelled.
