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.
