pinctrl: sunxi: Free configs in pinctrl_map only if it is a config map

Browse source

In the recently refactored sunxi pinctrl library, we are only allocating
one set of pin configs for each pinmux setting node. When the pinctrl_map
structure is freed, the pin configs should also be freed. However the
code assumed the first map would contain the configs, which actually
never happens, as the mux function map gets added first.

The proper way to do this is to look through all the maps and free the
first one whose type is actually PIN_MAP_TYPE_CONFIGS_GROUP.

Also slightly expand the comment explaining this.
