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.

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.

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.

This patch add the unit-address component to memory and flash
nodes. According to the DT specification, the unit-address of
a node must match the first address specified in the reg
property of the node.

The I2C controller nodes are the root of the I2C bus for that controller
and thus may have children nodes that represent the I2C devices on that
controller. Thus we need to specify the #address-cell & #size-cell
properties.

In stm32 dtsi linux files, uart generic node name is serial.
Rename uart node names of stm32 dtsi files from uart@ to serial@

Now that we can utilize label in the device tree we can convert to
getting the device name for the STM32 UART out of the device tree
instead of from Kconfig.

Add support for STM32L475xG SoC as a preliminary for
Discovery IOT board support.
stm32l476.dtsi file is now including stm32l475.dtsi
since STM32L476 SoC is a STM32L475 SoC with LCD support
