image_types_fsl.bbclass: do not create a partition from 0 to 1MB in i.MX sdcard

The bootrom boots from a fixed 1K offset so we don't need a partition
there and having one makes udev or kernel to probe for it and output
error messages in bootlog:

,----[ boot error messages ]

| EXT3-fs (mmcblk0p1): error: can't find ext3 filesystem on dev mmcblk0p1.
