Reduce the number of parameters of the function by moving inside
the decoding of the field 'config'.

While there:
- change the type of 'param' to 'unsigned int' to handle the extra
  values not in 'enum pin_config_param';
- change the type of 'arg' to 'u32' to avoid additional conversions
  and align to 'u32' the corresponding param of __stm32_gpio_set().
