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/

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.

ADC shell commands can be only executed on the property label

returning existing ADC Label.

The channel command has been extended with subcommands: id, positive,
and negetive. Some boards require positive input configuration before
measurement can be started.

Use dedicated shell macros so argument count can be validated before

Changed gain and reference commands to dictionary commands.
This change removes an obsolete look-up table (string <-> value)
for gain and reference commands.
Now, each modification of gain or reference value will require only
a dictionary command update.

Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.
Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.
To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:
- emit macros for all existing nodes in gen_defines.py, regardless
of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter

Make drivers multi-instance wherever possible using DT_INST_FOREACH.
This allows removing DT_HAS_DRV_INST in favor of making drivers just
do the right thing regardless of how many instances there are.
There are a few exceptions:
- SoC drivers which use CMake input files (like i2c_dw.c) or otherwise
would require more time to convert than I have at the moment. For the
sake of expediency, just inline the DT_HAS_DRV_INST expansion for
now in these cases.
- SoC drivers which are explicitly single-instance (like the nRF SAADC
driver). Again for the sake of expediency, drop a BUILD_ASSERT in
those cases to make sure the assumption that all supported SoCs have
at most one available instance is valid, failing fast otherwise.

Replace having dts_fixup.h files define DT_ADC_{0..2}_NAME with using
the new devicetree.h macros. We test to see what driver compat is
enabled via DT_HAS_COMPAT and set DT_DRV_COMPAT to that compat. Than we
can utilize the DT_INST_LABEL() macro to extract the name of the device.
We also replace the Kconfig ADC_{0..2} symbols with DT_HAS_DRV_INST.
This will allow us to remove those Kconfig symbols as this was the only
usage.
