Add phandle prop to reference any regulator that must
be enabled in order for the LPADC to function as intended.
Change LPADC driver to use this property if present.
LPADC on LPC55S36 depends on VREF peripheral, enable for this platform.

When reading multiple ADC channel in parallel, an ADC command chain will be
build. This is similar to a linked list, as every command references the
next command.
Before this patch every ADC command after the first, would always reference
this initial command. So that during execution only two commands (the last
and first) would be executed which resulted in readout of only two analog
values. As Zephyr expected more to come in, the `read_adc` function would
block endlessly.
The patch fixes the behaviour and allows a correct chain to build up.

To be consistent with the current NXP clocking scheme,
move the LPADC clocking code to the SOC files where
all of the other peripheral clocking is done.
Also remove any other SOC-specific code to the
respective SOC file and out of this driver.

Code for power level property was accidentally
removed by accident from driver in commit 9921c59f40

- Remove build asserts in favor of DT enums
- Remove power level property since it is unused by SDK
- Correct voltage ref value in DT to correspond to
chip specific values documented in reference manuals
instead of corresponding to SDK enum names.
- Fix SOC devicetrees affected by these changes.

The MCUX platform always uses pinctrl, there's no need to keep extra
macrology around pinctrl. Also updated driver's Kconfig options to
`select PINCTRL` (note that some already did).

Rewrite MCUX LPADC driver, to better utilize hardware.
the following changes have been applied:
- channel numbers now correspond to hardware channel command slots,
use "input_positive" and "input_negative" fields along with channel
definitions in dt-bindings/adc/mcux-lpadc.h to select a channel
- the number of channel command slots available is configurable via
CONFIG_LPADC_CHANNEL_COUNT
- Side A and side B channels are now supported
- differential channel mode is now supported
- ADC channels now are sampled via hardware, without additional
software triggering

Add support for side B channels in MCUX LPADC driver. Given
that no instances of the IP block have more than 8 a side channels,
use channel numbers over 8 to indicate side B channel is desired.

Refactors all of the ADC drivers to use a shared driver class
initialization priority configuration, CONFIG_ADC_INIT_PRIORITY, to
allow configuring ADC drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to preserve the
existing default initialization priority for most drivers. The
exceptions are lmp90xxx, mcp320x, and mcux_adc16 drivers which have
dependencies on GPIO, SPI, and/or DMA drivers and must therefore
initialize later than the default device priority.

reuse the lpc's lpadc driver for rt1170, modify the dts and add
some macro to shield some code of LPC series. Also add the
board support inside the tests/drivers/adc/adc_api/src/test_adc.c,
and a dts node:zephyr,user inside
