Introduce flash controller nodes for STM32 SoCs that are supported in
the flash driver. This is a precusor to converting the flash driver on
stm32 over to using device tree.

Where missing add compatible = "soc-nv-flash". Also added a label for
all the soc-nv-flash that we might use in the future.

This commits adds the "least common denominator" in the
stm32fX.dtsi files and fills the additional SPI nodes
in stm32fXYZ.dtsi files, only for the SOCs where boards
use the additional SPI peripheral.
We could add the rest SPI nodes in the stm32fXYZ.dtsi
files when we add SPI support to other boards.

This makes the SoC flash compatible with the common nonvolatile flash
YAML schema, and provides a write alignment. It mirrors work done on
nRF chips for the DFU subsystem.

Stop using CONFIG_I2C_x_DEFAULT_CFG to get the initial value. Since we
only support master mode we always default to it for initial config and
we get the bitrate from the device tree.

Add pinctrl node on stm32l4 soc dts files, including uart
pinctrl configurations. This is done thanks to <soc>-pinctrl.dtsi
file matching the <soc>.dtsi file
Populate stm32 l4 based boards dts files with references
to uart pinctrl nodes

In order to simplify maintenance of dts files for
stm32f4 series, introduce a stm32l4.dtsi file which
represent the smallest common denominator of IPs in
the family.
This allows to fix usart4 availability on stm32l432
which was not correct.
