tegra132: move common bootblock init into SoC code

The current 2 boards were setting up clocks and enabling
peripherals that apply to the SoC generically. Therefore,
move the common pieces into the SoC code.

BUG=chrome-os-partner:31105
BRANCH=None
TEST=Built and booted through depthcharge on ryu.
