arm64: configs: add toradex_defconfig

Add toradex_imx_v8.config which contains the differences to NXPs config
imx_v8_defconfig.

With this file toradex_defconfig can be generated with the following
commands:

make imx_v8_defconfig
scripts/kconfig/merge_config.sh -m .config arch/arm64/configs/toradex_imx_v8.config
make savedefconfig
cp defconfig arch/arm64/configs/toradex_defconfig
