Add a property for STM32 ADC to indicate which type of sequencer is used
by the device (fully configurable or not).
Add defines to help with this setting.

Remove temp-, vref- and vbat-channel from STM32 ADC nodes as it is not
used in the driver anymore.

Add two properties to define the STM32 ADC clock source:
- Clock source: synchronous or asynchronous
- Clock prescaler
By combining these two parameters, it will be possible to set the desired
ADC clock for most series.

Add a binding for STM32 ADC to specify the resolutions and all associated
register information (through a STM32_ADC_RES macro).

Boolean properties for STM32 ADC internal channels are not used anymore
and can be removed. It is replaced by channel number properties.

Add some bindings to define STM32 ADC internal channels for:
- Temperature
- Vref
- Vbat
The goal is to transfer information to the dts instead of inside the
ADC driver.

DTS property attributes are (by default) not required.
Explicitly specifying `required: false` is redundant.
Perhaps a warning to that effect would be useful.

Like other temperature or vrefint sensor, the stm32 mcu
also have a Vbat monitoring internal channels on ADC.
Add this entry to the device tree.
The vref is usually 3300mV present on the target board.

Add the Vref reference voltage in the DTS, so that the adc driver
can retrieve the value for conversion.

Introduce ADC properties which indicated if the ADC instances have
dedicated channels for the internal temperature sensor or voltage
reference.

Now that STM32 drivers are using pinctrl API, set pintrl-0 and
pintrl-names properties as required in order to report malformed
nodes description soon at build stage and avoid cryptic
DT api build error messages.

Move the devicetree bindings for Analog-to-Digital Converters (ADCs)
from dts/bindings/iio/adc to dts/bindings/adc as Zephyr does not have
an IIO layer.
