Add support for tegra20 arm7 boot processor. This processor is used to power on the Cortex A9 and transfer control to it. In tegra this processor is an ARM7TDMI not an ARM720T, but since we don't use cache it was easier to just reuse the ARM720T code as the processors are otherwise identical except for cache and MMU.

Another little nit, shouldn't have space before (
