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.
