[PATCH 1/2] pinctrl: baytrail: Fix selecting gpio pinctrl state

[Hans de Goede <hdegoede@redhat.com>]

For all the "score" pin-groups all the intel_pingroup-s to select
the non GPIO function are re-used for byt_score_gpio_groups[].

But this is incorrect since a pin-group includes the mode setting,
which for the non GPIO functions generally is 1, where as to select
the GPIO function mode must be set to 0.

So the GPIO function needs separate intel_pingroup-s with their own mode
value of 0.

Add foo_gpio entries for each function to byt_score_groups[] and make all
the byt_score_gpio_groups[] entries point to these instead to fix this.

The "sus" pin-groups got this correct until commit 2f46d7f7e959 ("pinctrl:
baytrail: Add pinconf group + function for the pmu_clk") added support for
the pmu_clk pins following the broken "score" model.

Add pmu_clk?_grp_gpio entries to byt_sus_groups[] and point to those
in byt_sus_gpio_groups[] to fix this.

Fixes: 2f46d7f7e959 ("pinctrl: baytrail: Add pinconf group + function for the pmu_clk")
