From: Jagan Teki jagan@amarulasolutions.com
Add initial devicetree support for i.MX6 Quad Sabresd board.
(1) Added config options CONFIG_OF_CONTROL=y CONFIG_DM_GPIO=y CONFIG_DM_MMC=y CONFIG_BLK is not set CONFIG_DM_MMC_OPS is not set CONFIG_PINCTRL=y CONFIG_PINCTRL_IMX6=y (2) Moved spl code to board/freescale/mx6sabresd/spl.c (3) Removed U-Boot proper board_mmc_init code, since mmc support through dtb (4) DM_GPIO and GM_MMC are undef for SPL, till SPL_OF_CONTROL support.
