imx6ulz_smm_m2b_defconfig, imx6ulz_smm_m2_defconfig and
imx6ulz_smm_m2d_defconfig are the same, except for the CONFIG_TARGET_
line.

I suggest introducing a <configs/imx6ulz_smm_m2.config> with the
standard part and then including this header file and the
CONFIG_TARGET_ line in each defconfig.

Take a look at some examples:

configs/imx6_dhcom_drc02_defconfig:#include <configs/dh_imx6.config>
configs/imx6_dhcom_pdk2_defconfig:#include <configs/dh_imx6.config>
configs/imx6_dhcom_picoitx_defconfig:#include <configs/dh_imx6.config>

The idea here is to simplify maintenance and prevent duplicate
defconfig settings.
