kbuild: generate lexer and parser during build instead of shipping
Recent kernel versions run flex and bison to generate lexers and
parsers from real source files such as *.l and *.y . This provides
better maintainability than version-controlling pre-generated C files
with a "_shipped" suffix.
This commit imports flex and bison rules from Linux, and deletes
pre-generated parsers and lexers.
Refer to the following commits in Linux:
- 033dba2ec06c ("kbuild: prepare to remove C files pre-generated by
flex and bison")
- 29c833061c1d ("kconfig: generate lexer and parser during build
instead of shipping")
- e039139be8c2 ("scripts/dtc: generate lexer and parser during
build instead of shipping")
