Warrior tegra build cicular dependencies

So adding the following to the tegra-minimal-initramfs.bbappend solves the problem,

EXTRA_IMAGEDEPENDS_remove = "u-boot"

And the problem here is that we in meta-mender add an dependency to U-boot for all images,

Which then results in a circular dependency since in the Tegra case you would have the follow chain:

U-boot -> tegra-minimal-initramfs -> U-boot
