[U-Boot] [PATCH V2 4/4] ARM: tegra: make use of negative ENV_OFFSET on NVIDIA boards

From: Stephen Warren <swarren at nvidia.com>
Use a negative value of CONFIG_ENV_OFFSET for all NVIDIA reference boards
that store the U-Boot environment in the 2nd eMMC boot partition. This
makes U-Boot agnostic to the size of the eMMC boot partition, which can
vary depending on which eMMC device was actually stuffed into the board.
