Harmonized asm linker configs.

Browse Source 
- All segments but CODE are optional and CODE is R/W. Both together allow to "just" write code/data without ever explicitly using a segment.

- Symbols are defined for the BSS. This allows to use/implement zerobss.

- The ZP memory area isn't artificially limited.
