Vincent Palatin 8dc20291b2 stm32: add 32-bit timer support ...

Some STM32 variants have a 32-bit timer in addition the bunch of 16-bit
timers.
Add the option to use the 32-bit timer as the system clock source to
lower the overhead of the timer code compared to a pair of 16-bit
timers.

BRANCH=none
BUG=none
TEST=run the EC on STM32F072 Discovery board with 32-bit TIM2 as the
clock source.
