d8a7c1f134 pinctrl/lantiq: fix pin number in ltq_pmx_gpio_request_enable
The mapping logic inside ltq_pmx_gpio_request_enable() was
broken. This only effected Falcon SoC.

3a6b04ca33 pinctrl/lantiq: add pin_config_group_set support
While converting all the boards supported by OpenWrt to OF
I noticed that this feature is missing. Adding it makes the
devicetrees more readable.

89377aa515 pinctrl: lantiq: Staticize non-exported symbols
Both ltq_pinctrl_dt_node_to_map() and ltq_pinctrl_dt_free_map() are not
referenced outside of this file. Make them static.

5c084ec820 pinctrl: lantiq: Remove ltq_pmx_disable() function
Current code adds empty ltq_pmx_disable() because pinmux_check_ops() requires
this callback to be defined.

This is not required since commit 02b50ce4cb
"pinctrl: make pinmux disable function optional".

Thus remove ltq_pmx_disable() function.

3f8c50c9b1 OF: pinctrl: MIPS: lantiq: implement lantiq/xway pinctrl support
Implement support for pinctrl on lantiq/xway socs. The IO core found on these
socs has the registers for pinctrl, pinconf and gpio mixed up in the same
register range. As the gpio_chip handling is only a few lines, the driver also
implements the gpio functionality. This obseletes the old gpio driver that was
located in the arch/ folder.
