The boot script appends values to certain variables such as
$extra_bootargs and $overlays.
If the final instruction of the boot script (dboot command)
fails, these variables contain the new values, plus the original
one. Since the user recovers the prompt, he may do a 'saveenv'
to save the environment, and the modified variables will be
saved, only to be enlarged again on the next boot.
This can lead to repeated strings on such variables.
Save the original value and restore it in case of failure on
the dboot command.

This adds support for U-Boot v2017.03 for all platforms (including CC8X).
For legacy v2015.04:
- Renames u-boot.inc as a versioned file only for v2015.04.
- Moves boot/install scripts from versioned folder into non-versioned
folder (since the scripts remain the same between versions).
For new v2017.03:
- Re-uses poky's u-boot.inc in rocko for v2017.03
- DEY recipe re-writes the do_compile for special U-Boot configuration
required for TrustFence.
- DEY recipe appends the do_deploy, for U-Boot scripts and deploy of
special TrustFence artifacts.
- Adds u-boot-dtb.xxx to UBOOT_CONFIG, required for new U-Boots.
- Adds CC8X scripts.
