Subject: stm32.h: Doxygen tweaks.

For some unfathomable reason, Doxygen happily believes in PCLK2, but
but not PCLK1, so Breathe can't find the docs for PCLK1, and all the
children are unhappy.  As a workaround, move all the Doxgyen crap into
__DOXYGEN_PREDEFINED_HACK sections immediately preceding the actual
definitions.
