imx28evk: Fix the first partition location
When the SD card is connected to the host PC it can be mounted as
/dev/mmcblk0 or /dev/sdX, depending on how the SD controller is connected to
/the PC.
In this case the first partition is /dev/mmcblk0p1, not /dev/mmcblk01.
So use the ${PART1} variable to correctly assign this location.
