The ADC is currently disabled and re-enabled multiple time during each
read. Enabling the ADC is not a free operation on some series and some
internal channels like VREFINT take even longer. This patch improve the
situation by removing the calls to adc_stm32_enable(), replacing it by a
single call just before triggering the conversion.
This also open the possibility to not reconfigure the ADC if it is
already configured, implemented in the following patches.

Entering deep sleep mode stops the source clock of the ADC module and
could corrupt the ongoing ADC conversion. This commit lets ADC driver
acquire the PM lock during the ADC operation (either single conversion
or repetitive scan) and release it when the ADC conversion stops.

Replace soc-specific pin functions with Zephyr pinctrl api functions for
pin-mux configuration in npcx adc driver. Please notice users need to
configure the corresponding pinctrl nodes in 'pinctrl-0' property in the
adc0 DT node. For example, if ADC0 and ADC2 channels are selected for
the application, please add the follwoings in your board DT layout file.
&adc0 {

Instead of selecting appropriate HAS_HW_NRF_* options for particular
nRF SoCs (and simulated nRF52 target), set their values basing on
information from devicetree.
Correct also semantics of those options so that they are set only when
a corresponding DT node is enabled. This allows using them directly in
Kconfig dependencies of Zephyr drivers for nRF peripherals. Update
appropriately these dependencies.

In npcx adc driver, we select 'Scan' (Multiple Channels Operation Mode)
mode by default. It means that selected channels in ADCCS will be
converted automatically. Then, read the measured data from CHNDAT
registers if EOCCEV (Event is set after all selected channels are
converted.) flag in ADCSTS is set.
But we enable the wrong interrupt type, INTECEN, during adc
initialization. Ec will send the interrupt after each channel in ADCCS
is converted. It has no harm to the current driver since the driver
reads all selected channels and turns off ADC converter only after
EOCCEV is set in ISR. But it does generate spurious interrupts.
This CL enables the correct interrupt type, INTECCEN, during adc
initialization. Ec only sends the interrupt after all of channels in
ADCCS are converted.

The ADC sampling of it8xxx2 needs to read each channel in sequence,
so it needs to wait for an interrupt to read data in the loop
through k_sem_take().
In test_adc.c, k_timer_start() is used in the interval test, so we
need to use polling wait instead of k_sem_take() to wait, otherwise
it will cause kernel panic.
k_is_in_isr() can determine whether to use polling or k_sem_take()
at present.

Previously this was expected to be equal to 1 at all times. This doesn't
play well with the sample or other users (e.g: adc_shell). Instead, we
should count the number of active channels in the bitfield, and ensure
