shuffle a few things around re: the BBL ST2302U based handhelds, give bbl338 its own map due to internal ROM etc. (#7584)
* shuffle a few things around re: the BBL ST2302U based handhelds, give bbl338 its own map due to internal ROM etc. * fake some interrupts on bbl338 * better document test draw command, so that we can verify we're in test mode
