flashmap: Add support for linker script generation
Flash map form bsp.yml could easily be inconsistent with linker scrip
memory regions.
This change aims to allow usage of sysflash.h header generate by newt tool
to be used by c preprocessor to automatically generate linker scrips that are
consistent with flash description from bsp.yml.
This simply excludes part of the header so only constants are exported.
