1. mcu/stm32: Calculate I2C timing register …

   STM32 F1,F4,L1 do have ClockSpeed filed in I2C initialization API,
   so it easy to specify requested clock speed for I2C.
   For all other devices ST HAL does not provide such field and
   expect that TIMINGR register value is precomputed.
   This value is specified in each BSP and is likely incorrect
   for some of them.
   
   This change introduces hic_speed to MCUs that has timing register and
   function that computes timing register base on requested speed and system
   clock.
   
   If timing register is specified in settings it is still being used to
   to configure I2C. If timing register setting is 0 hic_speed is used.
