If several ADCs are used and share a common clock property (for example
ADC1/2 prescaler value on STM32U5), none of them should be enabled when
the clock is set.
To that end, make sure to disable ADC at the end of the initialization,
it will be enabled later when necessary anyway.

The mcux_adc16 driver's read function fails to validate the user-provided
buffer size when `adc_sequence.options` are used (extra samplings).
The calculation erroneously considered only the size required for one
channel, neglecting the total number of channels in the sequence.
This leads to a **buffer overflow** when reading multiple channels.
Fix this by using `POPCOUNT(sequence->channels)` to determine the
correct channel count and ensure the buffer size is sufficient.

The burst length unit is bytes, not number of transfers. This had not been
an issue since the DMA driver historically ignored the values, but has now
become one since they are used and (most importantly for us) validated.

The Siwx91x ADC reference voltage is configurable rather than fixed.
Expose `ref_internal` in the device API so the driver can retrieve the

New nrfx release contains major rework of nrfx drivers
instantiation making it easier to integrate with dts nodes.
Now, nrfx driver instances can no longer be `const`
because they contain driver runtime state.
Additionally, all nrfx drivers return `errno` error codes
instead of deprecated `nrfx_err_t`.

- Currently, ADC driver does not implement any PM related constraints.
Due to this, when using it with PM enabled (example ieee802154, which
enabled PM by default), it will stall the system.
- Similar to pwm driver, disable standby when ADC is sampling. The
variable standby_disabled is just a flag to ensure that we disable (or
enable) standby only when ADC driver selects it. Otherwise, it is
possible to have a condition where ADC enabled PM and ieee802154
disables it.
- This follows what TI SDK ADC driver does [0].

Use STM32_CLOCK_INFO(), STM32_DT_INST_CLOCK_INFO(),
STM32_CLOCK_INFO_BY_NAME() and STM32_DT_INST_CLOCK_INFO_BY_NAME()
helper macros in STM32 drivers.
Using these macros ensure the clock division factor is properly
populated according to DT information. Prior these changes some
drivers only got the bus and bits position information and missed
the clock division information which is fine only when this division
factor information is 0.

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

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
