That must be adapted so that each internal channels

ADC4 is using CommonChannel config for the Sampling time.

The ADC module has four conversion groups, each one is set up as a zephyr
device. The start-up calibration is initiated globally for all groups
and it is run in each device init function. The ADC module supports post
calibration per group. Post calibration is run automatically after each
group acquires the samples.

Add CONFIG_CRC for building CRC related routines.
CRC routines are now being built for each application, whether used or
not and are add in the build system unconditionally.
Keep CONFIG_CRC enabled by default for now and until all users have
converted to use the new option.

New ADC driver for the TI CC13xx/CC26xx family.
ADC channel configurations are translated from Zephyr constants to
simplelink driverlib ones (e.g., sample times use a lookup table).
Async mode was also implemented & tested.

Set the synchronous clock mode to HCLK/1 (DIV1) or HCLK/2 (DIV2)
Both are valid common clock setting values.
The HCLK/1 (DIV1) is possible only if the ahb-prescaler = <1>
in the RCC_CFGR (see DTS).

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

Many device pointers are initialized at compile and never changed. This
means that the device pointer can be constified (immutable).

It is frequent to find variable definitions like this:
```c
static const struct device *dev = DEVICE_DT_GET(...)
```
That is, module level variables that are statically initialized with a
device reference. Such value is, in most cases, never changed meaning
the variable can also be declared as const (immutable). This patch
constifies all such cases.

The VREFINT and TEMPSENSOR internal channels have a stabilization time
after they are enabled. Right now this just causes the first measure to
be a bit off, however with PR #47691 which stops the internal channels
after each readout, this is something important to respect. Fortunately
the stabilization time is available as constants in the HAL, so just
wait the time specified by the constants.
Note that the VBAT internal channel does not have any stabilization
time.

This commit avoid re-enabling the ADC,
because this starts conversion.
According to the RefMan (RM0008) of the stm32F10x mcu,
enabling the ADC will start the conversion
if the ADC is already enabled. "Conversion starts when
this bit holds a value of 1 and a 1 is written to it."
That's not what we want.
