generated_dts_board.h is pretty redundant and confusing as a name. Call it devicetree.h instead. dts.h would be another option, but DTS stands for "devicetree source" and is the source code format, so it's a bit confusing too. The replacement was done by grepping for 'generated_dts_board' and 'GENERATED_DTS_BOARD'. Two build diagram and input-output SVG files were updated as well, along with misc. documentation. hal_ti, mcuboot, and ci-tools updates are included too, in the west.yml update.
