Yann Gautier 88ef0425da stm32mp1: add BSEC driver
The BSEC (Boot and Security and OTP control) is intended to control an OTP
(one time programmable) fuse box, used for on-chip non-volatile storage
for device configuration and security parameters.

Antonio Nino Diaz 09d40e0e08 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: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988 ("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.

Antonio Nino Diaz c3cf06f1a3 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

Yann Gautier a3d39cc763 stm32mp1: add an IO to read MMC devices
Whereas the GPT table is read with io_block, the binaries to be loaded
(e.g. BL33) cannot use it, as it is not suitable to read them block by
block, or the boot time would be very bad.
