pinctrl: Clean up headers

There is a few things done:
- include only the headers we are direct user of
- when pointer is in use, provide a forward declaration
- add missing headers
- group generic headers and subsystem headers
- sort each group alphabetically

While at it, fix some awkward indentations.

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).

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.
