The cc253x Makefile specifies SoC flavor

Browse source 
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

### SoC flavor (F256, F128, F64, F32) as the ID of the last flash bank (0...7)
### We assume F256, project Makefile can override

### ToDo:
### Fix --code-size accordingly
### Fix the bank allocator to play for all flavors

### Banking Guesswork:
### Generic examples do not specify banking.
### We automatically turn it on if its unspecified and if we are building with
