We can now use SDCC's __nonbanked feature

This allows us to reduce CODE footprint of SDCC projects
built with --model-huge. Use carefully!

* Added a facility which allows us to enable/disable the
  feature from the CPU dir (CC_CONF_NON_BANKED_OPTIMIZATION)
* Added the CC_NON_BANKED keyword to some platform files
  (expands to __nonbanked)
* Started using this for some examples
