Ricardo Salveti 7714c9a7aa pwm: stm32: Fix check for APB prescale
RCC_HCLK_DIV1 translates to 0x0 while apb_psc uses the value defined
by CONFIG_CLOCK_STM32_APB1/2_PRESCALER (range from 1 to 16).

Manually check if the defined prescaler is 1 or not and use that to
calculate the correct timer clock.

Erwan Gouriou 9413c8ba4d stm32: clean up after completion of transition to ll Clock control
Following migration of stm32f1xx series clock control driver to
STM32Cube LL API, cleanup stm32 code base in order to take into
account that this is the only clock driver available for stm32
family.

Erwan Gouriou 726d4dc437 drivers: stm32: clean up after stm23cube based clock control
After activation of cube based driver support on L4 and F3 series,
this commits performs the clean up of F3 and L4 relative code to
native clock control drivers.
Indirectly, it makes pwm driver supported de facto on F3 series

Erwan Gouriou 2ab8250c5b pwm: update stm32 pwm to support LL clock control driver
After introducing STM32Cube based clock control driver for
stm32 family, update stm32 pwm driver to support it.
Once supported across the whole family, a clean up will be done.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Erwan Gouriou 4827f2f386 pwm/stm32: add PWM driver for STM32 F1/F4/L4
Provide PWM driver for STM32 series F1/F4/L4.
Driver is ported on STM32Cube HAL and should support other STM32
series with minor updates.
Configuration is done so that PWM sample driver could be run on
all nucleo boards supporting PWM driver.
