    stmhal: Add option to free up TIM3 from USB VCP polling. · 66b96822
    Damien George authored
    This is a hack to free up TIM3 so that it can be used by the user.
    Instead we use the PVD irq to call the USB VCP polling function, and
    trigger it from SysTick (so SysTick itself does not do any processing).
    The feature is enabled for pyboard lite only, since it lacks timers.
