refactor(tegra132): deprecate platform 



The Tegra132 platforms have reached their end of life and are
no longer used in the field. Internally and externally, all
known programs have removed support for this legacy platform.

This change removes this platform from the Tegra tree as a result.

* During boot, USB3 and flash media (SDMMC/SATA) devices need
* access to IRAM. Because these clients connect to the MC and
* do not have a direct path to the IRAM, the MC implements AHB
* redirection during boot to allow path to IRAM. In this mode
* accesses to a programmed memory address aperture are directed
* to the AHB bus, allowing access to the IRAM. This mode must be
* disabled before we jump to the non-secure world.
