Since commit17d2100189("ARM: imx: Allow user to disable pinctrl"), the CONFIG_PINCTRL option is no longer implicitly selected, causing several i.MX SoC pinctrl drivers no longer getting selected by default. This causes boot regressions on the ARMv4, ARMv5, ARMv6 and ARMv7 i.MX SoCs. Fix it by selecting CONFIG_PINCTRL as before. This defeats the purpose of 7d210018914 ("ARM: imx: Allow user to disable pinctrl"), but it is the less invasive fix for the boot regressions. The attempt to build Layerscape without pinctrl can still be explored later as suggested by Arnd: "Overall, my best advice here is still to not change the way i.MX pinctrl works at all, but just fix Layerscape to not depend on i.MX. The reason for the 'select' here is clearly that the i.MX machines would fail to boot without pinctrl, and changing that because of Layerscape seems backwards."
