Tegra210: lock PMC registers holding CPU vector addresses

This patch locks access to the PMC registers which hold the CPU reset
vector addresses. The PMC registers are used by the warmboot code and
must be locked during boot/resume to avoid booting into custom firmware
installed by unknown parties e.g. hackers.
