Subject: [PATCH 1/2] pinctrl: utils : add support to pass config type in generic util APIs
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.
