For Tegra boards, the device-tree alias serial0 is used for the console
and so add the stdout-path information so that the console no longer
needs to be passed via the kernel boot parameters.
This has been tested on boards, tegra20-trimslice, tegra30-beaver,
tegra114-dalmore and tegra124-jetson-tk1.

The only boards that I have not modified are tegra114-roth and
tegra114-tn7 because these boards have two entries for console
in the *.dts file. AFAICT we cannot suppport multiple consoles
via the stdout-path and if a console is specified by the kernel
boot parameters then this sets the kernel variable
"console_set_on_cmdline" and prevents the stdout-path console
being registered. If there is a better way to handle these boards
via device-tree let me know.
