Tegra: smmu: add smmu_verify function

The SMMU configuration can get corrupted or updated by
external clients during boot without our knowledge.

This patch introduces a "verify" function for the SMMU
driver, to check that the boot configuration settings are
intact. Usually, this function should be called at the
end of the boot cycle.

This function only calls panic() on silicon platforms.

Tegra: TZDRAM setup from soc specific early_boot handlers

TZDRAM setup is not required for all Tegra SoCs. The previous bootloader
can enable the TZDRAM fence due to architectural improvements in the
newer chips.

This patch moves the TZDRAM setup to early_boot handlers for SoCs to
handle this scenario.

Tegra: memctrl_v2: fixup sequence to resize video memory

The previous sequence used by the driver to program the new memory
aperture settings and clear the non-overlapping memory was faulty.
The sequence locked the non-overlapping regions twice, leading to
faults when trying to clear it.

This patch modifies the sequence to follow these steps:

* move the previous memory region to a new firewall register
* program the new memory aperture settings
* clean the non-overlapping memory

This patch also maps the non-overlapping memory as Device memory to
follow guidance from the arch. team.
