This allows Tegra be included in a kernel build that supports multiple SoCs at once, which is useful for distro kernels. This change: * Moves Tegra's Kconfig into its own directory, as seems typical for multi-platform conversions. * Stops selecting some ARM errata that are incompatible with multi- platform. This requires that you use a bootloader that enables the workaround! * Deletes some headers and Makefile.boot that aren't needed now that we support multi-platform.
