pinctrl: baytrail: Fix selecting gpio pinctrl state
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 a new PIN_GROUP_GPIO macro which adds a foo_gpio entry to each
pin-group defined this way and update byt_score_gpio_groups[] to point
to the new foo_gpio entries.
The "sus" usb_oc_grp usb_ulpi_grp and pcu_spi_grp pin-groups are special
because these have a non 0 mode value to select the GPIO functions and
these already have matching foo_gpio pin-groups, leave these are unchanged.
The pmu_clk "sus" groups added in commit 2f46d7f7e959 ("pinctrl: baytrail:
Add pinconf group + function for the pmu_clk") do need to use the new
PIN_GROUP_GPIO macro.
Fixes: 2f46d7f7e959 ("pinctrl: baytrail: Add pinconf group + function for the pmu_clk")
