stm32mp1: do not include platform header files directly in drivers ...

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.

mmc: increase delay when initializing mmc ...

Running TF-A 2.0 and later seems to cause a regression on HiKey 620.

    NOTICE:  BL2: v2.0(release):v2.0
    NOTICE:  BL2: Built : 17:41:23, Dec 17 2018
    NOTICE:  acpu_dvfs_set_freq: set acpu freq success!ERROR:   CMD1 failed after 100 retries
    ERROR:   BL2: Failed to load image (-5)

The reason seems to be that during emmc enumeration when BL2 sends the command
    OCR_SECTOR_MODE | OCR_VDD_MIN_2V7 | OCR_VDD_MIN_1V7

it for some reason takes some more time to get a reply. So a delay with
mdelay(1), seems to not be enough any longer and therefore we increase it to
mdelay(10) instead which makes the device boot as expected again.

MULTI_CONSOLE_API fixes and cleanups

drivers/console: Reimplement MUTLI_CONSOLE_API framework in C ...

Now that we have switched to using the stack in MULTI_CONSOLE_API
framework functions and have factored all code involved in crash
reporting out into a separate file, there's really no reason to keep the
main framework code in assembly anymore. This patch rewrites it in C
which allows us to have a single implementation across aarch32/64 and
should be much easier to maintain going forward.

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.

plat/common/crash_console_helpers.S: Fix MULTI_CONSOLE_API support ...

Crash reporting via the default consoles registered by MULTI_CONSOLE_API
has been broken since commit d35cc34 (Console: Use callee-saved
registers), which was introduced to allow console drivers written in C.
It's not really possible with the current crash reporting framework to
support console drivers in C, however we should make sure that the
existing assembly drivers that do support crash reporting continue to
work through the MULTI_CONSOLE_API.

This patch fixes the problem by creating custom console_putc() and
console_flush() implementations for the crash reporting case that do not
use the stack. Platforms that want to use this feature will have to link
plat/common/aarch64/crash_console_helpers.S explicitly.

Also update the documentation to better reflect the new reality (of this
being an option rather than the expected default for most platforms).
