72ab6b29bf doc: doxygen: replace option alias with kconfig
Similar to Sphinx, @kconfig{} alias should be used in Doxygen docstring
in order to reference a Kconfig option. @option{} is still kept for
compatibility reasons.

8c4c72d213 drivers: adc: update to conform to API guidelines
When the async API is not enabled produce a link-time error rather
than a runtime error.  Also document the dependence on the option.

f234c5f876 drivers: adc: Introduce the adc_sequence_options::user_data field
Introduce the field that can be used to associate a given sampling
sequence with any other data needed in the sampling-done callback
function.
Adjust one ADC API test case that uses a sequence callback so that
it checks if this introduced field is propagated as expected.

Also clarify in the description of the `sequence` parameter of the
callback function that this parameter is not supposed to be supplied
to the CONTAINER_OF() macro, to avoid any further confusion in that
regard.

b7ce849307 drivers: adc: Make all API functions available
Change the way the `adc_read_async()` function is defined so that
the function is always available and appears in the generated
documentation but returns `-ENOTSUP` when `CONFIG_ADC_ASYNC` is not
enabled.

e18fcbba5a device: Const-ify all device driver instance pointers
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

4420c5ed40 adc: provide API to help with conversions
Gain values are specified with enumeration values that can't be used
to reverse the effects of scaling the input signal.  Provide a
function that reverses the effect of the gain by scaling a measured
value.

Also provide a function that converts a raw measurement captured with
a reference voltage and specific gain and resolution to the
corresponding voltage in millivolts.

6554a5e5b6 include: rearrange for standard use of extern "C" in various headers
Consistently place C++ use of extern "C" after all include directives,
within the negative branch of _ASMLANGUAGE if used.

The inclusion of the generated syscall files is placed outside the
extern "C" block as the generated file has its own extern "C" block.

Background from issue #17997:

Declarations that use C linkage should be placed within extern "C"
so the language linkage is correct when the header is included by
a C++ compiler.

Similarly #include directives should be outside the extern "C" to
ensure the language-specific default linkage is applied to any
declarations provided by the included header.
