ARM: Make it possible to use a custom bootblock implementation.

Tegra needs to use a custom bootblock implementation because it starts on a
coprocessor which uses ARMv4. It doesn't have the same control registers,
caches, etc., and the regular bootblock gets exceptions and dies.

BUG=None
TEST=Built for pit. With this and other changes, built and booted on nyan and
verified that it got into the bootblock.
BRANCH=None
