classes/image_types_fsl: Fix mxsboot image generation
>From OE-Core commit
8a9f249a9166347cc0468191ce130003e3d306e1:
If image type "foo" depends on image type "bar.xz", then dependencies
should be collected from the base image type (ie "IMAGE_DEPENDS_bar")
not from "IMAGE_DEPENDS_bar.xz".
IMAGE_DEPENDS_uboot.mxsboot-sdcard has uboot as base image type and
IMAGE_DEPENDS_uboot.mxsboot-sdcard = "foo" never will run.
Changing IMAGE_FSYPES to uboot-mxsboot-sdcard fix this issue and base
base will be uboot-mxsboot-sdcard.
