uniphier: set CONSOLE_FLAG_TRANSLATE_CRLF and clean up console driver ...

This console driver sends '\r' before 'n', not after.
It works, but the convention is "\r\n" (i.e. CRLF)

Instead of fixing it in the driver, set CONSOLE_FLAG_TRANSLATE_CRLF
to leave it to the framework.

uniphier: support console based on multi-console ...

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.

Remove duplicated definitions of linker symbols ...

Many parts of the code were duplicating symbols that are defined in
include/common/bl_common.h. It is better to only use the definitions in
this header.

As all the symbols refer to virtual addresses, they have to be
uintptr_t, not unsigned long. This has also been fixed in bl_common.h.

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.

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

Currently, the xlat region of the on-chip SRAM is always allocated
for all BL images.

The access to the on-chip SRAM is necessary for loading images from
a USB memory device (i.e. when updating firmware), so unneeded for
the usual boot procedure.

To avoid this waste, allocate the xlat region dynamically only for
BL2, and only when it is necessary.

The warm boot mailbox code is compiled if PROGRAMMABLE_RESET_ADDRESS

The warm boot mailbox is useless for UniPhier SoC family because BL1

then BL1 works as a pseudo ROM, so it is never executed in the warm
boot.

The reset vector address is not actually programmable for UniPhier
platform, but it should not hurt to enable PROGRAMMABLE_RESET_ADDRESS
to disable the mailbox and remove pointless plat_get_my_entrypoint.
