This patch sets the Memory Controller's TXN_OVERRIDE registers
for most write clients to CGID_ADR. This ensures ordering is maintained.
In some cases WAW ordering problems could occur. There are different
settings for Tegra version A01 v A02.

The GPU is the real consumer of the video protected memory region
and it needs to be in reset to pick up the new region.
This patch checks if the GPU is in reset before we program the new
video protected memory region settings.

This patch programs the Memory controller's control registers
to disable non-secure accesses to the TZRAM. In case these
registers are already programmed by the BL2/BL30, then the
driver just bails out.

This patch adds driver for the Memory Controller (v2) in the newer
Tegra SoCs. The newer hardware uses ARM's SMMU hardware instead of
the proprietary block in the past.
