      stmhal: Add PWM capability for LED(3) and LED(4) on pyboards. · a8a4b01a
      Damien George authored
      USB CDC no longer needs TIM3 (which was originally used for LED(4) PWM)
      and so TIM3 has been freed for general purpose use by the user.  Hence
      LED(4) lost its PWM capabilities.
      
      This patch reinstates the PWM capabilities using a semi-generic piece
      of code which allows to configure a timer and PWM channel to use for any
      LED.  But the PWM capability is only configured if the LED is set to an
      intensity between 1 and 254 (ie only when needed).  In that case the
      relevant timer is configured for PWM.  It's up to the user to make sure
      the timers are not used if PWM is active.
      
      This patch also makes sure that PWM LEDs are turned off using standard
      GPIO when calling led.off() or led.intensity(0), instead of just setting
      the PWM counter to zero.

      stmhal: Make TIM3 available for use by the user. · ea89b80f
      Damien George authored
      TIM3 is no longer used by USB CDC for triggering outgoing data, so we
      can now make it available to the user.
      
      PWM fading on LED(4) is now gone, but will be reinstated in a new way.

      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.
