stmhal: Disable MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE.
It uses RAM and on pyboard we are generally tight on RAM, so disable this optimisation for general builds. If users need the speed then they can build their own version. Maybe in the future we can have different versions of pyboard firmware built with different tradeoffs.
