This patch implements a handler for common SiP calls. A weak
implementation for the SoC-specific handler has been provided
which can be overridden by SoCs to implement any custom SiP
calls.

This patch converts the common SiP handler to SoC specific SiP
handler. T210 and T132 have different SiP SMCs and so it makes
sense to move the SiP handler to soc/t132 and soc/t210 folders.

This patch implements support for T132 (Denver CPU) based Tegra
platforms.
The following features have been added:
* SiP calls to switch T132 CPU's AARCH mode
* Complete PSCI support, including 'System Suspend'
* Platform specific MMIO settings
* Locking of CPU vector registers

This patch adds support to reserve a memory carveout region in the
DRAM on Tegra SoCs. The memory controller provides specific registers
to specify the aperture's base and size. This aperture can also be
changed dynamically in order to re-size the memory available for
DRM video playback. In case of the new aperture not overlapping
the previous one, the previous aperture has to be cleared before
setting up the new one. This means we do not "leak" any video data
to the NS world.
