tegra132: add bootblock_mainboard_early_init()
Instead of hard coding certain pieces of a board in the common chipset code provide a way to initialize things early in the bootblock path. Add a bootblock_mainboard_early_init() function before console init to performany necessary mainboard initialization early in the bootblock. BUG=chrome-os-partner:31104 BUG=chrome-os-partner:31105 BUG=chrome-os-partner:29981 BRANCH=None TEST=built both on rush and ryu. rush still behaves the same.
