[PATCH] arm: renesas: Enable preboot environment variable on all R-Car systems

[Marek Vasut]

Enable the 'preboot' variable on all R-Car systems. This variable can
optionally be set and contain a script which is executed before the
autoboot timeout starts. This can be used to run critical scripts or
similar tasks. By default, the "preboot" variable is empty.
