gpio: intel_gpio: Pass pinctrl device to pcr_clrsetbits32()

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().
