To allow transition to device tree based clock configuration on
stm32 targets, rework clock_control driver to use intermediate
STM32_ macros initially defined as the equivalent Kconfig macros
for now.
Propagate the change in all code using these macros.
The reason to introduce these new macros instead of configuring
Kconfig flags using dt kconfigfunctions is that we'll need
to be able to inform users that Kconfig flags are deprecated
once the whole family conversion is done, to encourage
out of tree users to adopt this new configuration scheme.
Note: For now STM32H7 series and code is excluded.
This is the same for some series specific code such as
PLL mul/div for L0/L1 and XTRE prescaler on F1 series.

The build infrastructure should not be adding the drivers subdirectory
to the include path. Fix the legacy uses that depended on that
addition.

move misc/util.h to sys/util.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

RCC device could be common to various STM32 series.
Until now, PLL handling code was set in series specific files,
even if it was driving the same device than another series.
Minimize code duplication by factorizing code between series
when possible.
With this change, some series get additional features by getting
access to code developed for other series.
Additionally, while renaming the files, remove the non informative
'x' to minimize file name length
