Yann Gautier 7ae58c6ba7 stm32mp1: use functions to retrieve some peripheral addresses
PWR, RCC, DDRPHYC & DDRCTRL addresses can be retrieved from device tree.
Platform asserts the value read from the DT are the SoC addresses.

Yann Gautier 447b2b137d stm32mp1: split clkfunc code
Create a new file stm32mp_clkfunc.c to put functions that could be common
between several platforms.

Yann Gautier e0a8ce5d0d stm32mp1: remove some dependencies on clocks and reset in drivers
Include all RCC, clocks and reset headers from stm32mp1_def.h
which if exported to the firmware through platform_def.h.
The same dependency removal is done in common code as well.
Some useless includes are also removed in stm32_sdmmc2 driver.

Mainly remove suffix 1 from prefix stm32mp1 in several macros and functions
that can be used in drivers shared by different platforms.

Yann Gautier c9d75b3cf9 stm32mp1: split code between common and private parts
Some parts of code could be shared with platform derivatives,
or new platforms.
A new folder plat/st/common is created to put common parts.

stm32mp_common.h is a common API aggregate.

Remove some casts where applicable.
Fix some types where applicable.
Remove also some platform includes that are already in stm32mp1_def.h.

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.
