board: freescale: drop CONFIG_DM_I2C undefs

Drop CONFIG_DM_I2C undefs from board header files, and make them
disabled on these boards in defconfigs instead.

Disabling on Kconfig symbol was done automatically with this script:

cd configs
files=(*ls1046a*)
files2=(*T104*RDB*)
files3=(ls1021atwr_*)
files4=("imx8mp_evk_defconfig phycore-imx8mp_defconfig")
combine=("${files[@]}" "${files2[@]}" "${files3[@]}" "${files4[@]}")
cd ..

for item in ${combine[*]}
do
   echo "Adjusting  $item"
   echo "# CONFIG_SPL_DM_I2C is not set" >> configs/$item
   make $item && make savedefconfig && cp defconfig configs/$item
done
