dts: imx51: fix sd card gpio polarity specified in device tree
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().
