stm32: add synchronous debug printf
Allow use of a synchronous debug printf instead of using the
full console task to save space. This can be turned on with
CONFIG_DEBUG_PRINTF, and will provide essentially a one-way
console for debugging. This is essentially expanding upon
the debug_printf work done for zinger.
BUG=chrome-os-partner:41959
BRANCH=none
TEST=tested with following CLs on glados_pd by verifying we
get a one-way console.
