image_types_fsl.bbclass: generates mxs' u-boot bootstream binaries

The mxs SoC family requires use of a bootstream in bootloader but at
this moment only SDCard format is supported. The image for use is
'u-boot.mxsboot-sdcard' and this is also the file extension of the
generated file beside of regular u-boot binary.
