[U-Boot] [PATCH 2/3] ARM: imx6q_logic: Enable Pin muxing in SPL

[Adam Ford <aford173@gmail.com>]

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.
