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.

yaml: fix properties syntax to 'mapping' instead of 'series' According to yaml syntaxic rules, 'properties' described in dts bindings yaml files could be seen as 'mapping'(key/value couple), instead of 'series' (list of single elements). yaml 'mappings' will then be converted by yaml python library as python 'dict' which will ease treatment (instead of current list as were before this commit). Same treatment is applied to 'inherits'. script extract_dts_inlcude is updated to take change of yaml_list structre into account. This allows some code simplification. Largest impact is yaml_collapse function which works now allow complete overload method on all the attributes of a yaml nodes. Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>

dts: yaml: Align serial driver clocks bindings The common uart.yaml defines an optional clocks property that can be overridden by specific serial driver bindings to be required. The description and generation attributes are duplicated. This fixes build warnings: extract_dts_includes.py: Merge of 'description': 'Clock gate control information' overwrites 'Clock gate information'. extract_dts_includes.py: Merge of 'generation': 'structures' overwrites 'define'. And introduces a different build warning, which is intended behavior: extract_dts_includes.py: Merge of 'category': 'required' overwrites 'optional'.
