The function pcr_clrsetbits32() expects a device with a P2SB parent device. In intel_gpio_direction_output() and intel_gpio_set_value() the device 'dev' is passed to pcr_clrsetbits32(), which is a gpio-controller with a device 'pinctrl' as parent. This does not match the expectations of pcr_clrsetbits32(). But the 'pinctrl' device has a P2SB as parent. Pass the 'pinctrl' device instead of the 'dev' device to pcr_clrsetbits32().
