fconf: Extract topology node properties from HW_CONFIG dtb

Create, register( and implicitly invoke) fconf_populate_topology()
function which extracts the topology related properties from dtb into
the newly created fconf based configuration structure 'soc_topology'.
Appropriate libfdt APIs are added to jmptbl.i file for use with USE_ROMLIB
build feature.

A new property which describes the power domain levels is added to the
HW_CONFIG device tree source files.

This patch also fixes a minor bug in the common device tree file
fvp-base-gicv3-psci-dynamiq-common.dtsi
As this file includes fvp-base-gicv3-psci-common.dtsi, it is necessary
to delete all previous cluster node definitons because DynamIQ based
models have upto 8 CPUs in each cluster. If not deleted, the final dts
would have an inaccurate description of SoC topology, i.e., cluster0
with 8 or more core nodes and cluster1 with 4 core nodes.

fconf: necessary modifications to support fconf in BL31 & SP_MIN

Necessary infrastructure added to integrate fconf framework in BL31 & SP_MIN.
Created few populator() functions which parse HW_CONFIG device tree
and registered them with fconf framework. Many of the changes are
only applicable for fvp platform.

This patch:
1. Adds necessary symbols and sections in BL31, SP_MIN linker script
2. Adds necessary memory map entry for translation in BL31, SP_MIN
3. Creates an abstraction layer for hardware configuration based on
fconf framework
4. Adds necessary changes to build flow (makefiles)
5. Minimal callback to read hw_config dtb for capturing properties
related to GIC(interrupt-controller node)
6. updates the fconf documentation

fconf: enhancements to firmware configuration framework

A populate() function essentially captures the value of a property,
defined by a platform, into a fconf related c structure. Such a
callback is usually platform specific and is associated to a specific
configuration source.
For example, a populate() function which captures the hardware topology
of the platform can only parse HW_CONFIG DTB. Hence each populator
function must be registered with a specific 'config_type' identifier.
It broadly represents a logical grouping of configuration properties
which is usually a device tree source file.

Example:
> TB_FW: properties related to trusted firmware such as IO policies,
base address of other DTBs, mbedtls heap info etc.
> HW_CONFIG: properties related to hardware configuration of the SoC
such as topology, GIC controller, PSCI hooks, CPU ID etc.

This patch modifies FCONF_REGISTER_POPULATOR macro and fconf_populate()
to register and invoke the appropriate callbacks selectively based on
configuration type.

Shared RAM region in the remote chip's memory is used as one of the
mailbox region (SCMI payload area) through which the AP core on the
local chip and SCP core on the remote chip exchange SCMI protocol
message during the initialization. Mark this region as non-cacheable in
the MMAP entry to prevent local AP core from reading stale data from the
cache.

Factor xlat_table sections in linker scripts out into a header file

TF-A has so many linker scripts, at least one linker script for each BL
image, and some platforms have their own ones. They duplicate quite
similar code (and comments).

When we add some changes to linker scripts, we end up with touching
so many files. This is not nice in the maintainability perspective.

When you look at Linux kernel, the common code is macrofied in
include/asm-generic/vmlinux.lds.h, which is included from each arch
linker script, arch/*/kernel/vmlinux.lds.S

TF-A can follow this approach. Let's factor out the common code into
include/common/bl_common.ld.h

As a start point, this commit factors out the xlat_table section.

Tegra186: add SE support to generate SHA256 of TZRAM

The BL3-1 firmware code is stored in TZSRAM on Tegra186 platforms. This
memory loses power when we enter System Suspend and so its contents are
stored to TZDRAM, before entry. This opens up an attack vector where the
TZDRAM contents might be tampered with when we are in the System Suspend
mode. To mitigate this attack the SE engine calculates the hash of entire
TZSRAM and stores it in PMC scratch, before we copy data to TZDRAM. The
WB0 code will validate the TZDRAM and match the hash with the one in PMC
scratch.

This patch adds driver for the SE engine, with APIs to calculate the hash
and store SE SHA256 hash-result to PMC scratch registers.
