Zephyr UART drivers offer very low-level functionality. Oftentimes,
it would be useful to provide higher-level wrappers around UART
device which would offer additional functionality. However, UART
driver irq callback routine receives just a pointer to (low-level)
UART device, and it's not possible to get to a wrapper structure
(without introducing expensive external mapping structures). This
is an indirect reason why the current UARt wrappers - uart_pipe,
console - are instantiated statically just for one underlying UART
device and cannot be reused for multiple devices.
Solve this by allowing to pass an arbitrary user data to irq
callback, set by new uart_irq_callback_user_data_set() function.
Existing uart_irq_callback_set() keeps setting a callback which
will receive pointer to the device.
While public API maintains compatibility, drivers themselves need
to be updated to support arbitrary user data storage/passing (as
legacy uart_irq_callback_set() functionality is now implemented in
terms of it).

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.

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

After introducing STM32Cube based clock control driver for
stm32 family, update stm32 serial driver to support it.
Once supported across the whole family, a clean up will be done.

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.

STM32Cube based implementation allows single driver file for
all stm32 based SoCs.
By maximizing code reuse, use of STM32Cube eases new SoCs
porting into Zephyr and provides better maintanability and
maturity.

Add driver for U(S)ART ports on STM32 MCUs. The driver implements basic
RX/TX functionality. Data transmission is implemented using polling. The
driver configures the port to use 8bit data transmission, 1 stop bit, no
parity control.
The driver exposes a public uart driver API and registers a single UART
device 'UART_0'. The device binds to USART1 peripheral and performs
required pinmux and clock control configuration. The device can be
initialized at the PRIMARY level, with default device priority.
The driver has been verified to work with a sample Hello World
application on a STM32F103 series MCU.
