soc/tegra: Restrict SoC device registration to Tegra
Commit 8a46828e623c ("soc/tegra: Register SoC device") added an initcall to register the SoC device on Tegra. However, that code is unrestricted and will run on all platforms, causing unwanted warnings. Fix this by first checking that we're running on hardware that supports the fuses block that we use to provide SoC information.
