dts: nrf: Add flash controller and alignment description for nRF52840 Added flash-controller description and moved flash description to it (for coherence). Added property for description of the flash alignment required by write operations. Thanks to that l-value FLASH_WRITE_BLOCK_SIZE macro will be generated. It is useful for any component uses the flash. Signed-off-by: Andrzej Puzdrowski <andrzej.puzdrowski@nordicsemi.no>

This binding gives a base FLASH description
properties:
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: bindings: compatible properties are required Any node which needs to generate defines from DTS must have a "compatible" property, because the corresponding "constraint" is what extract_dts_includes.py uses to match nodes with YAML files. There are a few YAML files in the tree that list compatible as "optional". Fix them. Signed-off-by: Marti Bolivar <marti@opensourcefoundries.com>

dts: flash: Add support for flash labels Added a label for soc-nv-flash nodes. Made some updates to the generation to maintain creating defines for properties like erase-block-size and write-block-size so they we get both FLASH_ERASE_BLOCK_SIZE and FLASH_${LABEL}_ERASE_BLOCK_SIZE (same for WRITE_BLOCK_SIZE).

dts: bindings: Introduce flash erase-block-size property Adds a new optional dts property to define the erase block size of a flash device. This will be used by the mcux flash driver to implement the flash page layout function. The value is set for all kinetis devices to match FSL_FEATURE_FLASH_PFLASH_BLOCK_SECTOR_SIZE.
