Use the helper that checks for overflows internally instead of manually
calculating the size of the new array.

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).

Add support to pass the config type like GROUP or PIN when using
the utils or generic pin configuration APIs. This will make the
APIs more generic.
Added additional inline APIs such that it can be use directly as
callback for the pinctrl_ops.
Changes from V1:
- Remove separate implementation for pins and group for
pinctrl_utils_dt_free_map and improve this function
to support both i.e. PINS and GROUPs.

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.
