Make sure that MX51_PAD_GPIO1_1 does not remain configure as ALT0/SD1_WP (it is out of reset). This is needed because of external pull-up resistor attached to that pad that, when left unchanged, will drive SD1_WP high preventing eSDHC1/eMMC from working correctly. To fix that add a pinmux configuration line configureing the pad to function as a GPIO. While we are at it, add a corresponding output-high GPIO hog in an effort to minimize current consumption.

Applied, thanks.
