"bool' is more suitable.

uniphier_emmc_is_over_2gb() is not boolean - it returns 1 / 0

Introduce macro 'CSS_SGI_CHIP_COUNT' to allow Arm CSS platforms with
multi-chip support to define number of chiplets on the platform. By
default, this flag is set to 1 and does not affect the existing single
chip platforms.

For multi-chip platforms, override the default value of
CSS_SGI_CHIP_COUNT with the number of chiplets supported on the
platform. As an example, the command below sets the number of chiplets
to two on the RD-N1-Edge multi-chip platform:

export CROSS_COMPILE=<path-to-cross-compiler>
make PLAT=rdn1edge CSS_SGI_CHIP_COUNT=2 ARCH=aarch64 all

RD-N1-Edge based platforms can operate in dual-chip configuration
wherein two rdn1edge SoCs are connected through a high speed coherent
CCIX link.

This patch adds a function to check if the RD-N1-Edge platform is
operating in multi-chip mode by reading the SID register's NODE_ID
value. If operating in multi-chip mode, initialize GIC-600 multi-chip
operation by overriding the default GICR frames with array of GICR
frames and setting the chip 0 as routing table owner.

The address space of the second RD-N1-Edge chip (chip 1) starts from the
address 4TB. So increase the physical and virtual address space size to
43 bits to accommodate the multi-chip configuration. If the multi-chip
mode configuration is detected, dynamically add mmap entry for the
peripherals memory region of the second RD-N1-Edge SoC. This is required
to let the BL31 platform setup stage to configure the devices in the
second chip.

PLATFORM_CORE_COUNT macro is set to be multiple of CSS_SGI_CHIP_COUNT
and topology changes are added to represent the dual-chip configuration.

In order the build the dual-chip platform, CSS_SGI_CHIP_COUNT macro
should be set to 2:
export CROSS_COMPILE=<path-to-cross-compiler>
make PLAT=rdn1edge CSS_SGI_CHIP_COUNT=2 ARCH=aarch64 all

This patch introduces a better separation between the trusted-boot
related properties, and the dynamic configuration DTBs loading
information.

The dynamic configuration DTBs properties are moved to a new node:
`dtb-registry`. All the sub-nodes present will be provided to the
dynamic config framework to be loaded. The node currently only contains
the already defined configuration DTBs, but can be extended for future
features if necessary.
The dynamic config framework is modified to use the abstraction provided
by the fconf framework, instead of directly accessing the DTBs.

The trusted-boot properties are kept under the "arm,tb_fw" compatible
string, but in a separate `tb_fw-config` node.
The `tb_fw-config` property of the `dtb-registry` node simply points
to the load address of `fw_config`, as the `tb_fw-config` is currently
part of the same DTB.

Introduce the Firmware CONfiguration Framework (fconf).

The fconf is an abstraction layer for platform specific data, allowing
a "property" to be queried and a value retrieved without the requesting
entity knowing what backing store is being used to hold the data.

The default backing store used is C structure. If another backing store
has to be used, the platform integrator needs to provide a "populate()"
function to fill the corresponding C structure.
The "populate()" function must be registered to the fconf framework with
the "FCONF_REGISTER_POPULATOR()". This ensures that the function would
be called inside the "fconf_populate()" function.

A two level macro is used as getter:
- the first macro takes 3 parameters and converts it to a function
  call: FCONF_GET_PROPERTY(a,b,c) -> a__b_getter(c).
- the second level defines a__b_getter(c) to the matching C structure,
  variable, array, function, etc..

Ex: Get a Chain of trust property:
    1) FCONF_GET_PROPERY(tbbr, cot, BL2_id) -> tbbr__cot_getter(BL2_id)
    2) tbbr__cot_getter(BL2_id) -> cot_desc_ptr[BL2_id]
