nvidia/tegra210: Enable RETURN_FROM_VERSTAGE to free up space 

All stages on this board are very close to the limit, so enable
RETURN_FROM_VERSTAGE so that we can overlap verstage and romstage to
use the available SRAM more effectively. (Coincidentally, this also
reduces verstage size quite a bit... maybe we should consider just
making this the default at some point, there are really no downsides.)
