Tegra: drivers: memctrl: introduce function to secure on-chip TZRAM

This patch introduces a function to secure the on-chip TZRAM memory. The
Tegra132 and Tegra210 chips do not have a compelling use case to lock the
TZRAM. The trusted OS owns the TZRAM aperture on these chips and so it
can take care of locking the aperture. This might not be true for future
chips and this patch makes the TZRAM programming flexible.
