The system configuration controller is mainly used to manage
the compensation cell and other IOs and system related settings.

The SYSCFG driver is in charge of configuring masters on the interconnect,
IO compensation, low voltage boards, or pull-ups for boot pins.
All other configurations should be handled in Linux drivers requiring it.

Device tree files are also updated to manage vdd-supply regulator.

PWR, RCC, DDRPHYC & DDRCTRL addresses can be retrieved from device tree.
Platform asserts the value read from the DT are the SoC addresses.

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.

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.

Change fdt_check_status function to fdt_get_status.
Update GPIO defines.
Move some functions in gpio driver, instead of dt helper file.
Add GPIO bank helper functions.
Use only one status field in dt_node_info structure including both status
and secure status.

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: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339 ("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.
