This change ports the software based SE context save routines.
The software implements the context save sequence for SE/SE2 and
PKA1. The context save routine is intended to be invoked from
the ATF SC7 entry.

This patch increases the MAX_MMAP_REGIONS build flag to allow
Tegra210 platforms to dynamically map multiple memory apertures
at the same time. This takes care of scenarios when we get multiple
requests to memmap memory apertures at the same time.

The non secure world would like to profile the boot path for
the EL3 and S-EL1 firmwares. To allow it to do that, a non-secure
DRAM region (4K) is allocated and the base address is passed to
the EL3 firmware.

This patch adds a library to allow the platform code to store the
tag:timestamp pair to the shared memory. The tegra platform code
then uses the `record` method to add timestamps.

MISRA Rule 10.3, the value of an expression shall not be assigned to
an object with a narrower essential type or of a different essential
type category.

The essential type of a enum member is anonymous enum, the enum member
should be casted to the right type when using it.

Both UL and ULL suffix equal to uint64_t constant in compiler
aarch64-linux-gnu-gcc, to avoid confusing, only keep U and ULL suffix
in platform code. So in some case, cast a constant to uint32_t is
necessary.

This patch saves the TZSRAM context and takes the SoC into System Suspend
from the "_wfi" handler. This helps us save the entire CPU context from
the TZSRAM, before entering System Suspend. In the previous implementation
we missed saving some part of the state machine context leading to an assert
on System Suspend exit.

rpi3: fix RPI3_PRELOADED_DTB_BASE usage

Add i.MX8 SoC SRTC/cpu-freq SIP runtime service support

Tegra downstream rebase 1.3.19

On i.MX8QM/i.MX8QX with system controller inside, the CPU's clock
rate is managed by SCFW(system controller firmware) and can ONLY be
changed from secure world, so SIP runtime service is needed for
setting CPU's clock rate, this patch adds cpu-freq SIP runtime service
support.

NXP's i.MX8 SoCs have system controller (M4 core) which takes
control of timer management, including watchdog, srtc and system
counter etc., other clusters like Cortex-A35 can send out command
via MU (Message Unit) to system controller for timer operation.

This patch adds timer IPC(inter-processor communication) support.

In case if `RPI3_PRELOADED_DTB_BASE` isn't defined explicitly with
proper pre-loaded DTB address, `add_define` macro defined in
`make_helpers/build_macros.mk` still supplies this definition to the
compiler like `-DRPI3_PRELOADED_DTB_BASE`, and it's obviously is set to
default value 1.

This simply leads to the wrong `MAP_NS_DTB` region definition (base_va
is set `0x1` instead of `0x00010000`) in `plat/rpi3/rpi3_common.c`:

Which causes aligment check to fail in `mmap_add_region_check()`:
VERBOSE: base_pa: 0x00000001, base_va: 0x00000001, size: 0x00010000
