Subject: dts: imx51: fix sd card gpio polarity specified in device tree

From: Dong Aisheng <aisheng.dong@freescale.com>

commit aca45c0e95dad1c4ba4d38da192756b0e10cbbbd upstream.

cd-gpios polarity should be changed to GPIO_ACTIVE_LOW and wp-gpios
should be changed to GPIO_ACTIVE_HIGH.
Otherwise, the SD may not work properly due to wrong polarity inversion
specified in DT after switch to common parsing function mmc_of_parse().
