Subject: rockchip: spi: Avoid setting the pinctrl twice
X-Git-Tag: v2016.03-rc1~216

rockchip: spi: Avoid setting the pinctrl twice

If full pinctrl is enabled we don't need to manually set the pinctrl in the
driver. It will happen automatically. Adjust the code to suit - we will
still use manual mode in SPL.
