The icmsg backend for ipc_service has a limitation of supporting only
on endpoint. This limitation is acceptable for many IPC instances.
However, some require to use multiple endpoints sharing a single
instance. To preserve the simple and the most efficient single-instance
backend, a separated backend is introduced implementing a wrapper
around icmsg core which adds multiple endpoints support.
There are two multi-endpoint ipc_service icmsg backends: one in the
initiator role, and the other one in the follower role. In a IPC
configuration one end of communication must be in the follower role
while the other one is in the initiator. The initiator initiates
an endpoint discovery handshake to establish enpoint identifiers for
requested endpoint names. The follower responds to requests sent by
the initiator.

For larger transfers DMA can be used enabling other tasks
to continue running. A threshold of 32 byte transfers
is about right and is defined threshold value for using DMA.
This does not currently support multiple SPI transactions changing
chip select with DMA (though the hardware supports this) currently.
Instead opting for the simpler first change of enabling one shot
DMA SPI transfers for those where the size warrants it.
Adds the loopback binding option to enable the spi_loopback test.

The ESP32 series MCUs allow to set a timeout which triggers an error
if the SCL line is unchanged for the specified amount of time.
By default, the ESP-IDF HAL sets the timeout to an arbitrary value of
10 times the bus cycle.
This is not sufficient for chips like the TI bq76952, which pulls the
SCL line low (clock stretching) for several 100 µs.
The timeout should also not be dependent on the chosen bitrate, as it
is defined by the time a chip needs for internal calculation before it
can provide requested data or continue communication.
This commit adds a property to devicetree to allow configuration of
the scl timeout. This value is set via direct register access, as the
ESP-IDF HAL does not provide access to the enable bit and does not
give any information about the maximum size of the timeout (defined
in I2C clock cycles in the register).

Microchip MEC172x has a modified eSPI SAF hardware implementation.
Hardware changes include multiple clock dividers for each SPI
flash device and data transfer using QMSPI local DMA.
espi reset interrupt is made a higer priority in MEC172x devicetree
because espi reset event resets all espi hardware and we don't
to want to service any other espi interrupt blocks when espi reset
occurs.

Executing code out of RAM on IT8xxx2 requires that the relevant
addresses be mapped onto the CPU's instruction memory bus, referred to
by ITE documentation as Instruction Local Memory (ILM). ILM mappings
configure blocks of RAM to be used for accesses to chosen addresses when
performing instruction fetch, instead of the memory that would normally
be accessed at that address.
ILM must be used for some chip features (particularly Flash
self-programming, to execute from RAM while writing to Flash), and has
historically been configured in the Flash driver. The RAM for that was
hard-coded as a single 4k block in the linker script. Configuring ILM
in the flash driver is confusing because it is used by other SoC code as
well, currently in code that cannot depend on the Flash being functional
or in hand-selected functions that seem performance-critical.
This change moves ILM configuration to a new driver and dynamically
allocates RAM to ILM in the linker script, allowing software use of the
entire 64k RAM depending on configuration. This makes ILM configuration
more discoverable and makes it much easier to correctly support the
CODE_DATA_RELOCATION feature on this SoC.
