scripts: dts: write new gen_defines.py
This is joint work with Kumar Gala (see signed-off-by).
This supports a new devicetree macro syntax coming. It's not really
worth mixing up the old and the new generation scripts into one file,
because:
- we aim to remove support for the old macros at some point, so it
will be cleaner to start fresh with a new script based on the old one
that only generates the new syntax
- it will avoid regressions to leave the existing code alone while
we're moving users to the new names
Keep the existing script by moving it to gen_legacy_defines.py and
changing a few comments and strings around. It's responsible for
generating:
- devicetree.conf: only needed by deprecated kconfigfunctions
- devicetree_legacy_unfixed.h: "old" devicetree_unfixed.h macros
Put a new gen_defines.py in its place. It generates:
- zephyr.dts
- devicetree_unfixed.h in the new syntax
Include devicetree_legacy_unfixed.h from devicetree.h so no DT users
are affected by this change.
