From: Stephen Warren <swarren@nvidia.com>

Enable all or none of Tegra support, rather than using separate Kconfig
options for individual SoCs. This will allow various conditional logic
to be simplified, as well as presenting fewer Kconfig options to the
user.

Once all use of ARCH_TEGRA_*_SOC has been replaced with ARCH_TEGRA, the
SoC-specific options will be removed.

Signed-off-by: Stephen Warren <swarren@nvidia.com>

I'll follow this up with patches for driver/memory, iommu, clk, pinctrl
and sound/soc which remove use of ARCH_TEGRA_*_SOC, and finally with a
series to remove those config options from the Tegra tree; that can be
applied once everything else is merged together.
