arm64: tegra132: tegra210: Remove old arm64/stage_entry.S

This patch removes the old arm64/stage_entry.S code that was too
specific to the Tegra SoC boot flow, and replaces it with code that
hides the peculiarities of switching to a different CPU/arch in ramstage
in the Tegra SoC directories.

TEST=Built Ryu and Smaug. !!!UNTESTED!!!
