By default for all ABx500 family chip, pin default mode is selected by clearing corresponding bit in GPIOSELx register except for pins which support alternate function, in this case, corresponding bit must be set. But, due to an unlogical hardware implementation, for one particular pin (GPIO11) reverse setting must be done. For that, update the alternate function array by declaring that this pin supports alternate function.
