rockchip: add an fdt parsing stub for platform param ...

The Rockchip ATF platform can be entered from both Coreboot and U-Boot.
While Coreboot does submit the list of linked parameter structs as
platform param, upstream u-boot actually always provides a pointer
to a devicetree as parameter.
This results in current ATF not running at all when started from U-Boot.

To fix this, add a stub that checks if the parameter is a fdt so we
can at least boot and not get stuck. Later on we can extend this with
actual parsing of information from the devicetree.

rockchip: Fix GICv2 interrupts ...

After the removal of deprecated interfaces in TF 2.0 the migration to
the new GIC driver interfaces was done incorrectly in rk3328 and rk3368:
2d6f1f01b141 ("rockchip: Migrate to new interfaces").

In the GICv2 driver it is mandated that all interrupts are Group 0
interrupts. This patch simply moves all Group 1 interrupts to Group 0.

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.

drivers/console: Link console framework code by default ...

This patch makes the build system link the console framework code by
default, like it already does with other common libraries (e.g. cache
helpers). This should not make a difference in practice since TF is
linked with --gc-sections, so the linker will garbage collect all
functions and data that are not referenced by any other code. Thus, if a
platform doesn't want to include console code for size reasons and
doesn't make any references to console functions, the code will not be
included in the final binary.

To avoid compatibility issues with older platform ports, only make this
change for the MULTI_CONSOLE_API.

Standardise header guards across codebase ...

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

rockchip: Move to MULTI_CONSOLE_API ...

This patch changes all Rockchip platforms to use the new
MULTI_CONSOLE_API. The platform-specific plat_crash_console
implementations are removed so that the platform can use the ones from
the common platform code instead.

Also change the registers used in plat_crash_print_regs. The existing
use of x16 and x17 has always been illegal, since those registers are
reserved for use by the linker as a temporary scratch registers in
intra-procedure-call veneers and can never be expected to maintain their
values across a function call.
