[U-Boot] [PATCH 3/3] ARM: imx6q_logic: Remove legacy pinmuxing code from board file.

With the OCRAM expanded to 256KB and the SPL_PINCTRL enabled with
-u-boot.dtsi entries to include the pinmuxing in SPL, the manual
code setting up the pinmux can go away.

This patch removes the legacy pinmuxing code from the board file.
