Add initial support for the AD4170-4, AD4190-4, and AD4195-4 24-bit
ADCs, including reference selection, programmable gain amplifier, ADC
conversion modes, configurable analog inputs, filter settings, and both
bipolar and unipolar operation. Supports internal and external buffered
references, and operation from a 4.75-5.25V analog supply and a
1.7-5.25V digital supply.

Some series like F1, F3, N6 and U3 use an ADC prescaler defined in the RCC.
Instead of adding specific properties in the RCC driver, use the secondary
clock system to configure the prescaler.
The ADC driver now configures the clocks depending on their presence and
their name. Three clocks can be defined:
- the register clock (mandatory for all series)
- the kernel clock (depends on series)
- the prescaler value (depends on series)

Devices which use AIN (COMP, LPCOMP, SAADC) don't use pinctrl to
configure their pins, thus pinctrl can't manage pin retention like
is done for other devices. Thus for now, add manually disabling
pin retention to the drivers.
In the future, we should probably use pinctrl for these inputs
as well, at which point this commit can be reverted.

In STM32 ADC binding, rename the possible values of the sequencer and
oversampler properties to use lowercase string, similar to the internal
regulator.
Adapts the driver and the dtsi with the new values.
Fixes a macro issue in the driver. Since the value from the dtsi didn't
start with internal_regulator_, the reconstruction of the defines by
the macro ANY_ADC_INTERNAL_REGULATOR_TYPE_IS was missing this prefix and
the comparison failed. Add a new argument to the IS_EQ_STRING_PROP to be
able to insert such a prefix.

The general ADC documentation states, that it is possible to use the

converted. This change fixes this issue as it now also checks if a callback

Introduce a streaming APIs for ADC devices.
Two new APIs are added to the adc_driver_api: submit and get_decoder.
Added decoder following APIs: get_frame_count, get_size_info, decode,
has_trigger.
Supported triggers are:
- ADC_TRIG_DATA_READY
- ADC_TRIG_FIFO_WATERMARK
- ADC_TRIG_FIFO_FULL
Supported operations to be done on trigger:
- include - whatever data is associated with the trigger
- nop - do nothing with data associated with the trigger
- drop - clear data associated with the trigger
Some changes to the linker scripts were needed to add decoder APIs.

The ADC driver API already supports ADC readings which can return signed
values, these are differential readings. In Nordic's datasheet, we have
a mode called "single ended", but its just a name. "Single ended" is a
differential reading, with the negative channel tied to GND. This is not
compatible with zephyrs definition of a single ended reading.
To support Nordic's "single ended" mode, the user must configure
a differential reading, with the negative input tied to ground, which
the saadc driver can then use to configure the reading as Nordic SAADC
"single ended", and return negative values as expected.

The stm32u3x header files defines LL_ADC_SINGLE_ENDED but not
LL_ADC_DIFFERENTIAL as the device doesn't support differential mode. The
driver only checked for LL_ADC_SINGLE_ENDED and assumed that when that was
defined, LL_ADC_DIFFERENTIAL would also be defined.
Check for both when figuring out which calibration type will be required.

The SAMPLERATE register can be used as a local timer instead
of triggering individual SAMPLE tasks. When SAMPLERATE.MODE is set
to Timers, it is sufficient to trigger SAMPLE task only once in order
to start the SAADC and triggering the STOP task will stop sampling.
The SAMPLERATE.CC field controls the sample rate.
The SAMPLERATE timer should not be combined with SCAN mode and
only one channel should be enabled when using the internal timer.

This Kconfig does not belong in the ADC folder, because there is not
actually a zephyr ADC driver for this. Also, remove HAS_MCUX_ADC_ETC as
well because it is a useless config.
The cmake line to pull in this driver from the SDK in the zephyr repo is
totally unnecessary. If a user wants to use this SDK driver they can add
it to their build like any other SDK driver or any other
external code module. Zephyr should not be a cesspool of random build
glue for random pieces of code.

The original code process causes the following two issues:
1. The first sample is always 0 because the `ctx` sequence in `data` is
assigned the input sequence until the `adc_context_start_read`. As a
result, the `while (channels) { ... }` loop is not executed, and
`adc_enable_measurement` is not called.
2. Since the `ctx` sequence in `data` is assigned in
`adc_context_start_read`, which occurs after the `while (channels) {
... }` loop, the ADC samples the previously set channel.
