Introduces a new mcux lpspi shim driver to be used on the imxrt soc.
This shim driver leverages heavily from the mcux dspi shim driver
because the MCUXpresso SDK provides similar APIs for the lpspi and dspi
peripherals.

Calculate proper initial PTP clock divisors based on the MCK value.
Additionally do not allow adjusting the rate of the clock. This does not
seem to work properly with current gPTP rate adjustment algorithm.
Having proper PTP clock divisors and callbacks that allow getting,
setting and adjusting current time is sufficient for proper gPTP
support.

Major rework of the mcux adc16 driver to convert it to the new adc api.
Currently supports a subset of the api features including synchronous
and asynchronous reads, and consecutive reads triggered by the kernel
timer.
Does not yet support some of the channel configuration options such as
gain and reference voltage because the hardware only allows these
options to be configured by peripheral instance rather than by channel.
The values are currently hardcoded in the driver, but in the future we
could introduce some flexibility per instance via device tree
attributes.
Does not yet support consecutive reads triggered by a hardware timer.

This commit adds translation layers to make nrfx drivers for the nRF
ADC (nRF51 series) and SAADC (nRF52 series) peripherals accessible via
the Zephyr's API. The SAADC peripheral is accessed using nrfx HAL only
as it turns out that usage of the nrfx driver in this case would be
inconvenient and would unnecessarily complicate the shim.

This commit replaces the API for ADC drivers with a reworked one.
As requested in the issue #3980, the adc_enable/adc_disable functions
are removed. Additionaly, some new features are introduced, like:
- asynchronous calls
- configuration of channels
- multi-channel sampling
Common parts of code that are supposed to appear in each implementation
of the driver (like locking, synchronization, triggering of consecutive
samplings) are provided in the "adc_context.h" file to keep consistency
with the SPI driver. Syscalls are no longer present in the API because
the functions starting read requests cannot use them, since they can be
provided with a callback that is executed in the ISR context, and there
is no point in supporting syscalls only for the channels configuration.
"adc_api" test is updated and extended with additional test cases,
with intention to show how the API is supposed to be used.
"adc_simple" test is removed as it does not seem to add much value.
