We need per device header includes to make the per target documentation
generation work properly. The dispatch headers are to dispatch to the
_target_ not directly to the final implementation, remember, the final
required headers for each may be multiple files, plus extra definitions!
to remove variations, redundancies, add missing, fix errors. All c files
refer only to the dispatch style headers in /include/stm32. Those headers
#include memorymap.h and cm3/common.h. All references to
these are removed from the family specific headers. Ethernet untouched as
it appears incomplete.
Added dummy spi.c for F0/F3. Fix some doxygen anomalies.
