Cleanup and preparation commit for linker script generator. Zephyr linker scripts provides start and end symbols for each larger areas in the linker script. The symbols _image_rom_start and _image_rom_end corresponds to the group ROMABLE_REGION defined in the ld linker scripts. The symbols _image_rodata_start and _image_rodata_end is not placed as independent group but covers common-rom.ld, thread-local-storage.ld, kobject-rom.ld and snippets-rodata.ld. This commit align those names and prepares for generation of groups in linker scripts. The symbols describing the ROMABLE_REGION will be renamed to: _image_rom_start -> __rom_region_start _image_rom_end -> __rom_region_end The rodata will also use the group symbol notation as: _image_rodata_start -> __rodata_region_start _image_rodata_end -> __rodata_region_end Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>
