This add regulator driver for Smartbond DA1469X SOC.
Driver can control VDD, V14, V18, V18P, V30 rails,
full voltage range supported by SOC is covered.
For VDD, V14, V18, V18P DCDC can be configured.
Special VDD_CLAMP (always on) and VDD_SLEPP are added
to allow configuration of VDD in sleep modes.

Add an option to drive inactive columns to inactive state rather than
high impedance. This is useful if the matrix has isolation diodes for
every key, as it allows the matrix to stabilize faster and the API for
changing the pin value is more efficient than the one to change the pin
configuration.

Only RTC can be used as the idle timer for cortex-m systick. Set the
chosen node as RTC by default.
The idle timer will be enabled only if PM management is set.

Add soc power management for the STM32F4x chips.
One low power state is added supported by all chips from the family -
the Stop mode with voltage regulator in low-power mode.
The Stop mode for STM32F chips has to work with the IDLE timer -
CORTEX_M_SYSTICK_IDLE_TIMER, because PLL and HSI are disabled in the
Stop mode (Systick is not clocked). The only possible wakeup source is
RTC, which works as a IDLE timer for the Systick.
The exit latency may need to be adjusted per system, depending on the
system tick frequency and other variables.

On STM32WL, the backup memory is defined as part of the TAMP peripheral.
This seems to be a deviation from the stm32 family where this memory is
defined as part of the RTC.
The STM32WL reference manual shows that tamp_pclk is connected to
rtc_pclk. This means that the clock required to run the TAMP peripheral
is the same as the RTC's. A quick port of BBRAM on STM32WL is achieved
by instanciating the bbram device as a child of the RTC and by modifying
the address offset to the first backup register from the rtc base
address.

This commit introduces the SOF host DMA driver.
This driver is used by NXP platforms in the context of
SOF's host component to copy data from the host memory
to the firmware (local) memory. This is possible because
NXP platforms can access the host memory directly w/o
an actual DMA engine.

Adds a clock control device for a PWM node, allowing the PWM
to be controlled using the clock control API.
It is a similar idea to the device driver in linux:

Split the common keyboard scanning code out of the ITE specific driver
and use the generic code instead.
Note that this changes few timing defaults, the change is not
significant though so I suspect there's no difference in practice.

Setting slew-rate property is not supported on Kinetis KE series
and the value will not have effect, so this property should not
be required.
We are also planning to reuse the Kinetis pin control binding and
associated driver for NXP S32K1xx devices, which doesn't support
setting the slew-rate rate as well.

The icmsg and icmsg_me backends has limitations in context of
concurrent access to single instance. Some limitations are:
* sending by more thread at the same time may cause -EBUSY
* allocating TX buffer will cause errors in other threads that want
to allocate before first thread sent the message,
* during no-copy receive, when RX buffer is on hold receiving is
totally blocked.
This backend resolves those limitations by adding dynamically allocated
buffers on shared memory next to ICmsg circular buffer. The data is
passed using those buffers, so concurrency is not a problem. The ICmsg
is used only to pass short 2-byte messages containing references to
those buffers. The backend also supports multiple endpoint.
The ipc/icmsg_me sample was modified to support this backend.
