Subject: u-boot-toradex: add inc to generate U-Boot default environment

Including u-boot-toradex-env.inc will generate a uEnv.txt text
file containing the default environment of the U-Boot binary.
This is useful for Toradex Easy Installer to write the default
environment using the "u_boot_env" property.
