pinctrl: re-order struct pinctrl_map
The lookup key in struct pinctrl_map is (.dev_name, .name). Re-order the struct definition to put the lookup key fields first, and the result values afterwards. To me at least, this slightly better reflects the lookup process. Update the documentation in a similar fashion. Note: PIN_MAP*() macros aren't updated; I plan to update this once later when enhancing the mapping table format to support pin config to reduce churn.
