The `LOG_ERR` will spam the log if the window is low e.g. 1 ms.
Also the PWM capture callback will be called with an error, which allows
handling and logging the error if desired.

If the value in the period_cycles variable exceeds UINT16_MAX, a 16-bit
timer will return an error code 134. An error message was added to
indicate that the value does not fit into the 16-bit timer register.
An error message advising developers to reduce the value to 16-bit
simplifies the process, allowing them to understand immediately that
reducing the value will resolve the issue.

Previously the pwm capture only support capturing on channel 1
and 2, because the slave mode controller was used, which uses
the signal TIxFP which is not available for channel 3 and 4.
This commit adds optional support for four channel capturing by
changing the method of capturing PWM signals to not use the
slave mode controller to reset the counter register. Instead the
counter is reset in the ISR. This will result in a slight loss
of accuracy but is still within an acceptable range.

If a timer is left running on an stm32mp1, (most likely) on the next run
the timer is stuck.
A simple timer reset before initialization fixes the issue.

Some STM32 timers have more than one interrupt available.
When such timer is used it's likely that the first found interrupt
will not be the proper, 'cc' interrupt for input capture.
Existing implementation always connected the first irq, which worked
for timers with single, 'global' interrupt but broke input capture
for advanced timers with more interrupts.
Improve the IRQ connection logic by connecting the 'cc' interrupt
if it exists. Only if not found use the fallback mechanism of taking the
first index

Extends STM32 PWM driver to support capturing pulse width, period,
or both.
The approach used is based on the PWM Input sections in reference
manual RM0351 by ST in the chapters on timers.
The LL library by ST is used for all extensions to the driver.
Only the disco_l475_iot1 board was available for testing on hardware,
using tests/drivers/pwm/pwm_loopback.
Since timers are a generic component, it is assumed that other STM32
boards will behave the same

Prescaler was misplaced in pwm binding, instead of timers binding.
For example, TIM6/TIM7 doesn't have PWM capability,
but have a prescaler.
This change also prepares the introduction of timer based counter
(which requires prescaler at timer level)
For compatibility reason temporarily use pwm prescaler if it exists,
otehrwise use timers prescaler.
And thus avoid to avoid breaking boards out of tree.

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.
