ARM: tegra: dependencies for ARM .init_time cleanup

This patch is a dependency for Sebastian Hesselbarth's series that
cleans up the ARM machine descriptor's .init_time hook. It may also end
up being a dependency for cleanup/development in the Tegra tree, and
hence is contained in its own topic branch, to allow conflicts to be
easily resolved.
