rpi3: Add mem reserve region to DTB if present

rpi3: Add mem reserve region to DTB if present ...

When a device tree blob is present at a known address, instead of, for
example, relying on the user modifying the Linux command line to warn
about the memory reserved for the Trusted Firmware, pass it on the DTB.

The current code deletes the memory reserved for the default bootstrap
of the Raspberry Pi and adds the region used by the Trusted Firmware.

This system replaces the previous one consisting on adding
``memmap=16M$256M`` to the Linux command line. It's also meant to be
used by U-Boot and any other bootloader that understands DTB files.

libfdt: Remove current version ...

The current version of libfdt (1.4.2) has been modified to integrate it
in this repository. In order to do a clean import it is needed to remove
the current version first.

juno: Increase BL2 max size ...

Version 1.4.7 of libfdt is bigger than the current one (1.4.2) and the
current reserved space for BL2 in Juno isn't enough to fit the Trusted
Firmware when compiling with clang or armclang.

The definitions FAIL_CONTROL_*_SHIFT were incorrect, they have been
fixed.

The types tzc_region_attributes_t and tzc_action_t have been removed and
replaced by unsigned int because it is not allowed to do logical
operations on enums.

Also, fix some address definitions in arm_def.h.

Multi-console: Deprecate the `finish_console_register` macro ...

The `finish_console_register` macro is used by the multi console
framework to register the `console_t` driver callbacks. It relied
on weak references to the `ldr` instruction to populate 0 to the
callback in case the driver has not defined the appropriate
function. Use of `ldr` instruction to load absolute address to a
reference makes the binary position dependant. These instructions
should be replaced with adrp/adr instruction for position independant
executable(PIE). But adrp/adr instructions don't work well with weak
references as described in GNU ld bugzilla issue 22589.

This patch defines a new version of `finish_console_register` macro
which can spcify which driver callbacks are valid and deprecates the
old one. If any of the argument is not specified, then the macro
populates 0 for that callback. Hence the functionality of the previous
deprecated macro is preserved. The USE_FINISH_CONSOLE_REG_2 define
is used to select the new variant of the macro and will be removed
once the deprecated variant is removed.

All the upstream console drivers have been migrated to use the new
macro in this patch.

NOTE: Platforms be aware that the new variant of the
`finish_console_register` should be used and the old variant is
deprecated.

broke verbose (V=1) builds on Windows. This patch fixes it by adding

qemu: increase PLAT_QEMU_DT_MAX_SIZE to 1 MiB ...

Since upstream QEMU commit 14ec3cbd7c1e ("device_tree: Increase
FDT_MAX_SIZE to 1 MiB"), which is included in release v2.12.1
and later, BL2 initialization fails with the following error (-3 is
-FDT_ERR_NOSPACE):

 ERROR:   Invalid Device Tree at 0x40000000: error -3

Increase PLAT_QEMU_DT_MAX_SIZE accordingly.

plat/arm/scmi: introduce plat_css_get_scmi_info API ...

The default values of 'plat_css_scmi_plat_info' is not applicable for
all the platforms. There should be a provision to let platform code to
register a platform specific instance of scmi_channel_plat_info_t.

Add a new API 'plat_css_get_scmi_info' which lets the platform to
register a platform specific instance of scmi_channel_plat_info_t and
remove the default values.

In addition to this, the existing 'plat_css_scmi_plat_info' structure
is removed from the common code and instantiated for the platforms that
need it. This allows for a consistent provisioning of the SCMI channel
information across all the existing and upcoming platforms.
