pinctrl: add utility functions for add map/configs Some of pincontrol driver needs the utility function to create map list. The utility function needed for adding mux, configs etc. In place of duplicating this in each driver, add the common utility function in common file and use from device specific driver. This will reduce the duplicating of code across drivers. Changes from V1: - Add this files in this patch and add common utility APIs to here. Changes from V2: - Nothing in code. - Added Reviewed by Stephen.

pinctrl: Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map, since it does not depend on device tree despite the current name. This will enforce a consistent naming in pinctr-utils.c and will make it clear it can be called from outside device tree (e.g. from ACPI handling code).
