This patch adds some common helper code to support a lightweight
platform parameter passing framework between BLs that has already been
used on Rockchip platforms but is more widely useful to others as well.
It can be used as an implementation for the SoC firmware configuration
file mentioned in the docs, and is primarily intended for platforms
that only require a handful of values to be passed and want to get by
without a libfdt dependency. Parameters are stored in a linked list and
the parameter space is split in generic and vendor-specific parameter
types. Generic types will be handled by this code whereas
vendor-specific types have to be handled by a vendor-specific handler
function that gets passed in.

The -Wshift-overflow=2 option enables checks for left bit shifts.
Specifically, the option will warn when the result of a shift will be
placed into a signed integer and overflow the sign bit there, which
results in undefined behavior.
To avoid the warnings from these checks, the left operand of a shift can
be made an unsigned integer by using the U() macro or appending the u
suffix.

The project has been renamed from "Arm Trusted Firmware (ATF)" to
"Trusted Firmware-A (TF-A)" long ago. A few references to the old
project name that still remained in various places have now been
removed.
This change doesn't affect any platform files. Any "ATF" references
inside platform files, still remain.

The legacy console is gone. Re-add the console support based on the
multi-console framework.
I am still keeping the putc, getc, and flush callbacks in
uniphier_console.S to use plat/common/aarch64/crash_console_helpers.S
The console registration code already relies on that C environment
has been set up. So, I just filled the struct console fields with the
callback pointers, then called console_register() directly. I also
re-implemented the init function in C to improve the readability.
Removing the custom crash console implementation has one disadvantage;
we cannot use the crash console on very early crashes because
crash_console_helpers.S works only after the console is registered.
I can live with this limitation.
Tested on my boards, and confirmed this worked like before.

These errors are asynchronous and cannot be directly correlated with the
exact current running software, so handling them in the same EL is not
critical. Handling them in TF-A allows for more platform specific
decoding of the implementation defined exception registers
