Tegra186: system resume from TZSRAM memory
TZSRAM loses power during System suspend, so the entire contents are copied to TZDRAM before Sysem Suspend entry. The warmboot code verifies and restores the contents to TZSRAM during System Resume.
This patch removes the code that sets up CPU vector to point to TZSRAM during System Resume as a result. The trampoline code can also be completely removed as a result.

Tegra186: disable PROGRAMMABLE_RESET_ADDRESS
This patch disables the code to program reset vector for secondary CPUs to a different entry point, than cold boot. The cold boot entry point has the ability to differentiate between a cold boot and a warm boot, that is controlled by the PROGRAMMABLE_RESET_ADDRESS macro. By reusing the same entry point, we can lock the CPU reset vector during cold boot.

NOTE: Future SoCs will have to define these macros to keep the drivers functioning.

Sanitise includes across codebase
Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them).
For example, this patch had to be created because two headers were called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988b9 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems.
Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

Tegra186: save/restore BL31 context to/from TZDRAM
This patch adds support to save the BL31 state to the TZDRAM before entering system suspend. The TZRAM loses state during system suspend and so we need to copy the entire BL31 code to TZDRAM before entering the state.
In order to restore the state on exiting system suspend, a new CPU reset handler is implemented which gets copied to TZDRAM during boot. TO keep things simple we use this same reset handler for booting secondary CPUs too.

Tegra186: power on/off secondary CPUs
This patch add code to power on/off the secondary CPUs on the Tegra186 chip. The MCE block is the actual hardware that takes care of the power on/off sequence. We pass the constructed CPU #, depending on the MIDR_IMPL field, to the MCE CPU handlers.
This patch also programs the reset vector addresses to allow the CPUs to power on through the monitor and then jump to the linux world.

Tegra186: platform support for Tegra "T186" SoC
Tegra186 is the newest SoC in the Tegra family which consists of two CPU clusters - Denver and A57. The Denver cluster hosts two next gen Denver15 CPUs while the A57 cluster hosts four ARM Cortex-A57 CPUs. Unlike previous Tegra generations, all the six cores on this SoC would be available to the system at the same time and individual clusters can be powered down to conserve power.
