The STM32 G0, G4, H7, L0, L4, WB and WL series have hardware support for
oversampling. This patch adds support for it, using the oversampling
value provided in the adc sequence. The result is shifted right
accordingly to not change the resolution of the measured value, like it
is done on other ADC drivers.

Commit c045cbd336 added support for internal voltage reference source,

Also change the code to keep the existing paths so that VREFINT and
TEMPSENSOR can be used at the same time.

The STM32H7 series has a special ADC, which is calibrated
on the factory. The calibration values are stored in flash
and must be retrieved upon powering up the device.
Failure to calibrate the device leads to missing codes in
the ADC readings.

This commit it to resolve following bugs:
* Operands don't affect result.
* Logical dead code in stm32_adc driver.
Above mentioned bugs were solved by adding parenthesis and
changed the method of comparing. Since comparison of ADC
channel_id with the channel may cause loss of value.
So instead of direct comparison, introduced a mechanism to
convert channel constant to a decimal using
__LL_ADC_CHANNEL_TO_DECIMAL_NB() and strips away
the INTERNAL_CH bit and then compare with channel_id.
fix:
* zephyrproject-rtos/zephyr#35130
* zephyrproject-rtos/zephyr#35136

ADC emulator is designed to be used in tests on native_posix board. It
supports 1-16 bit resolution range and all GAINs from enum adc_gain.
Reference voltages and number of emulated channels are set through dts.
Using special API from drivers/adc/adc_emul.h it is possible to set
constant voltage value returned by given ADC channel or set custom
function which allows to simulate complex output.
Also reference voltages can be changed in runtime using the API.
The CL also includes:
- Add adc definitions of ADC emulator in
tests/drivers/adc/adc_api/src/test_adc.c for supporting test suites.
- Add test for ADC emulator API in tests/drivers/adc/adc_emul/

For multiple channels detection, channels variable was compared with
the output of find_lsb_set which actually is a decimal number.
Since channel is a bitfield the comparison was not behaving as
expected (detecting several channels while only one channel was used).

the test.

NPCX7 includes a 10-bit resolution Analog-to-Digital Converter (ADC). Up
to 10 voltage inputs can be measured and a internal voltage reference
(VREF), 2.816V (typical) is used for measurement. It can be triggered
automatically in Autoscan mode. Each input channel is assigned a
separate result register, which is updated at the end of the conversion.
The CL also includes:
— Add npcx adc device tree declarations.
— Zephyr adc api implementation.
— Add adc definitions of npcx7 in
tests/drivers/adc/adc_api/src/test_adc.c for supporting test suites.

This part of common code for ADC drivers, the adc_context_enable_timer()
function, was still converting sampling interval values to milliseconds
(the only option available at the time this code has been created) when
setting up the kernel timer, consequently limiting the maximum sampling
frequency to 1000 samples per second. This patch switches the routine
to specifying the interval in microseconds, to remove this limitation.
