dts: arm: Add base DTS and YAML definitions This patch adds the base DTS and YAML files that may be referenced by SoCs. The device tree files provide base definitions for the more well known ARMV7M device nodes. These files are meant to be included in SoC vendor specific device tree files. The YAML files provide definitions for the contents of device tree node that contain information that will be parsed and used for configuration in the system. DTS files define hardware and software configuration and YAML files provide the markers for knowing which pieces need to be extracted.

dts: Align uart "baud-rate" property to device tree spec "current-speed" Devicetree.org specifies that serial devices property used to set baud rate is "current-speed", while zephyr uses "baud-rate". Align property name in order to keep zephyr dts files compatible with device tree specification and could be re-used from/to Linux for instance. We also cleanup a few SoCs that set "baud-rate" in the SoC dts and not the board.

dts: Add label property to uart.yaml Add optional label property to be generated as part of the UART yaml spec. This lets us use the label string in a device tree to generate the device name (for example CONFIG_UART_STM32_PORT_1_NAME). Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
