ARM: imx6q_logic: Enable Pin muxing in SPL
With the 256KB of OCRAM available to SPL now, there should be enough room to enable the pinmuxing in SPL from the device tree. This patch enables SPL_PINCTRL et al and adds the serial and usdhc pin mux references to the -u-boot.dtsi file so the pins can be configured from the device tree.
