It is not an error if the clock source is already enabled. This
may happen if a bootloader has used the peripheral and not
de-initialized it before booting the application.

Make use of ABUS support in the pinctrl driver to allocate
analog buses, rather than hard-coding bus 0 in the ADC driver.

Move all adc driver api structs into an iterable section, this allows us
to verify if an api pointer is located in compatible linker section.

The current driver initializes the IADC with the default configuration
(IADC_INITSINGLE_DEFAULT), which aligns the data to the right.
To correctly read the 12-bit sample, it should be masked from the right
instead.

Only 12-bit resolution is currently available in the driver,
and each of the 16-bit samples store the actual data
aligned to the left.
A sample should be shifted 4 bits to the right to allow
proper interpretation.

The adc_driver_api structure provides .ref_internal
which previously was unset.
Now .ref_internal is set to the proper value.
