The .data field in struct of_device_id is used as a const member so it's inappropriate to attach struct s32_pinctrl_soc_info with of_device_id because some members in s32_pinctrl_soc_info need to be filled by pinctrl-s32cc at runtime. For this reason, struct s32_pinctrl_soc_info must be allocated in pinctrl-s32cc and then create a new struct s32_pinctrl_soc_data in order to represent const .data in of_device_id. To combine these two structures, a s32_pinctrl_soc_data pointer is introduced in s32_pinctrl_soc_info. Besides, use of_device_get_match_data() instead of of_match_device() since the driver only needs to retrieve the .data from of_device_id.
