stmhal: Disable MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE.

dpgeorge · dpgeorge · commit ad33e2465c24 · 2015-01-24T23:45:37.000Z
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.
