This commit aligns TWIM shim to utilize memory-region property.
The memory-region is not required property that enables user
to specify placement of dma buffers in memory region.
It is done by assigning to memory-region property,
phandle to node with zephyr,memory-region and mimo-sram compatible.
When memory-region property is not specified for given
instance, buffer is placed in default RAM region with other data.

There are two different i2c node properites `zephyr,flash-buf-max-size`
and `zephyr,concat-buf-size`. In the end max value of that two is used
to define size of the message buffer.
It's redundant to store both values in device config structure.
Changed config structure to contain only bigger value.

Refactor the ESP32 target SOCs together with
all related boards. Most braking changes includes:
- changing the CONFIG_SOC_ESP32* to refer to
the actual soc line (esp32,esp32s2,esp32s3,esp32c3)
- replacing CONFIG_SOC with the CONFIG_SOC_SERIES
- creating CONFIG_SOC_FAMILY_ESP32 to embrace all
the ESP32 across all used architectures
- introducing CONFIG_SOC_PART_NUMBER_* to
provide a SOC model config
- introducing the 'common' folder to hide all
commonly used configs and files.
- updating west.yml to reflect previous changes in hal

- use CONFIG_HAS_HW_NRF_* symbols consistently in nRF multi-instance
drivers when creating particular driver instances
- remove unnecessary hidden Kconfig options that indicated the type of
peripheral to be used by a given instance (e.g. SPI, SPIM, or SPIS)
and enabled proper nrfx driver instance; instead, use one option per
peripheral type and include the corresponding shim driver flavor into
compilation basing on that option (not the one that enables the nrfx
driver as it was incorrectly done so far in some cases)

The eSPI, I2C, and SPI emulators use devicetree macros to build an array
of devices on the virtual bus. Currently, they will add device nodes that
are not status-okay. This leads to linker errors because the respective
device drivers would not have instantiated device structs for these
nodes --assuming the driver was even compiled. This can be frustrating
if nodes need to be disabled for debugging or configuration purposes.
Update the bus emulators to only consider status-okay nodes by changing
the macros used to iterate over bus devices.

In order for TCA954X driver to work well, we know that
mux root must be initialized before channels.

- Ensuring that this condition is met at build.
- Document needed values for menuconfig to help user.
- Edit these values for TCA954X test sample

Previous commit added support of large transactions on I2C v2,
this commit implements some changes to also add support

to put the code in the right source files.

The NPCX I2C controller has a port-controller hierarchy and the driver
is split in two files, with separate device struct and init functions.
These are currently initialized at the same level and priority, so the
actual order depends on what the linker does.
To avoid relying on the linking order, add a dedicated priority option
for the port that is set to go after the normal I2C one by default.
Found this by building with CONFIG_CHECK_INIT_PRIORITIES.
