95b1d586b9 soc: arm: Use HEAP_MEM_POOL_ADD_SIZE KConfig options
Kconfig options with a HEAP_MEM_POOL_ADD_SIZE_ prefix should be used to
set the minimum required system heap size. This helps prevent
applications from creating a non-working image by trying to set a too
small value.

1f2180e8ff drivers: adc: adc_sam0: fix c20 and c21 reference not setting
drivers: adc: adc_sam0: fix c20 and c21 reference not setting

On c20 and c21 variants, the adc_sam0 driver is failing to honor the
enable-protected status of the REFCTRL register when writing the channel
config's reference into it. This causes the reference to never be set
when adc_sam0_channel_setup is called since the ADC is not disabled
prior to the write. Fix it by adding the
ADC_SAM0_REFERENCE_ENABLE_PROTECTED definition to the c20 and c21 soc.h
files. This effectively disables the ADC during writes to the REFCTRL
register, thus honoring the enable-protected behavior of this register.
I'm assuming ADC_SAM0_REFERENCE_ENABLE_PROTECTED exists for this type
of situation and therefore this was the approach taken. After making
the change, I was able to verify proper ADC readings by measuring
voltage on an ADC pin and observing correct values. Reverting back prior
to this change, running the same test yields reading 0's.

ee15b1ff05 soc: atmel: same5x: Disable cache
The sam0 CMCC configure Cortex-M cache controller. However, it is not
clear how the cache management should be performed. It is nor clear if
instructions like SCB_EnableICache can be used. In this case, if cache
management should be made only by CMCC it may require a dedicated
implementation.

Besides above, the CPU_CORTEX_M4 do not define cache by default which
can signal a bad configuration in tree since the SOC_SERIES_SAME54 do
not define which caches should be available.

This force cache controller disable to avoid issues.

a5fd0d184a init: remove the need for a dummy device pointer in SYS_INIT functions
The init infrastructure, found in `init.h`, is currently used by:

- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices

They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:

```c
struct init_entry {
	int (*init)(const struct device *dev);
	/* only set by DEVICE_*, otherwise NULL */
	const struct device *dev;
}
```

As a result, we end up with such weird/ugly pattern:

```c
static int my_init(const struct device *dev)
{
	/* always NULL! add ARG_UNUSED to avoid compiler warning */
	ARG_UNUSED(dev);
	...
}
```

This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:

```c
static int my_init(void)
{
	...
}
```

This is achieved using a union:

```c
union init_function {
	/* for SYS_INIT, used when init_entry.dev == NULL */
	int (*sys)(void);
	/* for DEVICE*, used when init_entry.dev != NULL */
	int (*dev)(const struct device *dev);
};

struct init_entry {
	/* stores init function (either for SYS_INIT or DEVICE*)
	union init_function init_fn;
	/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
	 * to know which union entry to call.
	 */
	const struct device *dev;
}
```

This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.

**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

f450153c64 soc: arm: atmel_sam0: improved samd20/samd21/samr21 clocking mechanism
There are some issues with the current version of the code, mainly the
improper use of the internal OSC8M as a source for the DFLL48m without
division. The DFLL48M is designed to accept a maximum of ~33KHz
at it's input, as higher values will bring the multiplier down,
leading to instability.

Also added the following features:
* Support for external HF oscillator (XOSC)
* Support for crystal/external oscillators on XOSC32K/XOSC
* Automatic dividers/multiplier computation based on DT cpu frequency
* Support for user configurable NVM wait states
* Added option to skip clock (re)initialization (bootloader usecase).

Tests were performed on a custom SAMD20G18 board using different clock
sources and cpu frequencies.
Clocks were routed to GPIO pins and observed on a scope.
According to the datasheet, architecture is identical on D21/R21.

Due to the nature of the internal architecture and the fact that
DFLL48M is not really meant to output anything other than 48MHZ
some combinations of requested DT cpu frequency and source
frequency will not result in a perfect match.

Mostly insipred by the SAML21 implementation.
