Some Series were calculating the pll output frequency from an
clock source index instead of the clock source frequency.
This commit resolves this issue for l0, l1.
get_pllout_frequency() is only used for PLLCLK, therefore remove it.
F2, F4, and F7 have several pll dividers and might decide to implement
these as clock sources won't need PLLCLK.

The SOC specific implementations of the clock_stm32_ll_common driver
included the PLL specific functions only when PLL was selected as sysclock.
This commit changes the condition from "STM32_SYSCLK_SRC_PLL"
to "defined(STM32_PLL_ENABLED)".
As a result the pll could also be used as peripheral clock source
in case it is not the sysclock.

Similarly to what was done on U5 and H7 clock_control drivers, enable
device clock source selection.
This is done by:
-providing implementation for clock_control_configure().
-updating clock_control_get_rate() to support various possible clock
sources (SYSCLK, PLLCLK, LSE, LSI, HSI, HSE).
-providing enable_clock() to verify requested clock source exists and
is enabled.
-adding LSI and LSE device tree based initialization to
set_up_fixed_clock_sources().

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Introduce a set_up_pll configuration function and make PLL configuration
an elementary step of the whole system clock configuration.
To implement this new, function make use of the existing series specific
files which allows series specific configuration when required.

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 entropy driver needs to use the SYSCFG block to control VREF on
the STM32L0. Clock the block if the entropy driver has been enabled.

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
