Randall Spangler af12f2f58c stm32: Support DMA-based UART output ...

This reduces the number of UART interrupts by a factor of 12, and
reduces the overall interrupt rate on STM32 by a factor of 2.

BUG=chrome-os-partner:20485
BRANCH=none (not required for pit branch)
TEST=Boot pit.  Ctrl+Q pauses debug output; Ctrl+S resumes it.
     'crash divzero' still prints a full crash dump.
     And util/makeall.sh passes builds all platforms and passes tests.
