tegra132: use pre-existing reset API
coreboot already has a reset API. Utilize it by selecting HAVE_HARD_RESET. The tegra132 boards have to provide the hard_reset() implementation as that involves board-specific bits. The tegra132 code then provides a cpu_reset() routine that just promotes that call to a hard_reset(). For the existing tegra132 boards remove the unnecessary files from the build. BUG=chrome-os-partner:30784 BRANCH=None TEST=Ensured hard_reset() does something on Ryu.
