Thierry Reding a2686766c8 soc/tegra: Implement runtime check for Tegra SoCs
Subsequent patches will move some of the initialization code from SoC
setup code to regular initcalls. To prevent breakage on other SoCs in
multi-platform builds, these initcalls need to check that they indeed
run on Tegra.
