George Oikonomou 29090a3dda The cc253x Makefile specifies SoC flavor 
This will help us slowly add better support for smaller SoCs
instead of just assuming that all cc253x SoCs are F256

- We build for F256 by default but the project Makefile can override this
- We currently ignore this when passing --code-size. This is a ToDo
- The bank allocator always assumes 7 banks. Once we fix --code-size above this will be irrelevant
