ARM: tegra: rework boot scripts
Update the common Tegra boot scripts in the default environment to a) Make use of the new "test -e" shell command to avoid some error messages. b) Allow booting using the sysboot command and extlinux.conf. This allows easy creation of boot menus, and provides a simple interface for distros to parameterize/configure the boot process.
