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

Including u-boot-toradex-initial-env.inc will generate a uEnv.txt
for newer U-Boot versions using U-Boot's u-boot-initial-env
Makfile target. It essential does what u-boot-toradex-env.inc did
before.

Note: Since there is now support for an exported environment in
upstream U-Boot, we should upstream the OE logic to the official
U-Boot too.
