    stmhal: Improve efficiency of SysTick IRQ and HAL_Delay. · 34e43c7e
    Damien George authored
    SysTick IRQ now increases millisecond counter directly (ie without
    calling HAL_IncTick).  Provide our own version of HAL_Delay that does a
    wfi while waiting.  This more than halves power consumption when running
    a loop containing a pyb.delay call.  It used to be like this, but new
    version of HAL library regressed this feature.
