 NewState : new state of the DMA channel remapping. This
parameter can be:
 ENABLE : Enable fast mode plus driving capability for
selected I2C pin
 DISABLE : Disable fast mode plus driving capability for
selected I2C pin
Return values
 None.
Notes
 For I2C1, fast mode plus driving capability can be enabled on
all selected I2C1 pins using
SYSCFG_I2CFastModePlus_I2C1 parameter or
independently on each one of the following pins PB6, PB7,
PB8 and PB9.
 For remaing I2C1 pins (PA14, PA15...) fast mode plus driving
capability can be enabled only by using
