The CH32V003 has a 8 channel, 10 bit onboard ADC. Add an immediate
mode driver and the appropriate pinctrl bindings. Note that the
CH32V003 GPIO pins have both a floating input and an analogue input
mode, and the pinctrl is needed to put the pin in analogue mode.

SHIM Nordic modification for the ADC driver controlling the SAADC
peripheral. Replaced HAL based implementation in favor of nrfx driver.
As a next step, it is planned to implement a feature that will allow
the peripheral SAADC timer to be used for sampling, and for this it is
necessary to use the nrfx driver in this SHIM.
This will allow more accurate and faster sampling than the kernel
mechanism currently provides.

For a long time (since version 3.3.0) nrfx contained an incorrectly
defined symbol NRF_SAADC_8BIT_SAMPLE_WIDTH that was set to 8 for nRF54L
and nRF54H Series SoCs, which was probably only true for very early
engineering revisions of those. Based on this, the adc_nrfx_saadc driver
was incorrectly writing consecutive 8-bit samples in supplied buffers,
cutting off the highest 8 bits of the results. And for sequences with
multiple channels, it was even causing that the results written as
16-bit words by hardware were partially overwritten in next iteration.
In nrfx 3.12.0 (see commit f46798fa55)
this was finally corrected - the symbol is now deprecated and it is
always set to 16. This commit is a follow-up to the above and removes
parts of adc_nrfx_saadc that now became dead code to prevent further
confusion regarding 8-bit sampling.

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.

The ADC has a dedicated interface for communicating with the DMA.
The ADC module provides four interrupt sources (one for each
conversion result storage register) which can be configured to
source the DMA trigger.

Several drivers checked for the presense and availability of data cache
through Kconfig symbol. This is supported according to the current
documentation, but the symbol DCACHE masks two types of cache devices: arch
and external caches. The latter is present on some Cortex-M33 chips, like
the STM32U5xx. The external dcache is bypassed when accessing internal
SRAM and only used for external memories.
In commit a2dd232410 ("drivers: adc: stm32: dma support") the rationale
for gating dcache for adc_stm32 behind STM32H7X is only hinted at, but
reason seems to be that it was the only SOC the change was tested on. The
SOC configures DCACHE=y so it is most likely safe to swap the SOC gate for
DCACHE.
The DCACHE ifdefs are now hidden inside the shared stm32_buf_in_nocache()
implementation.

Add initialization of `ret` to avoid reports of uninitialized variable
being returned. This variable normally gets initialized while the loop
iterates over channels, but potentially it could be left uninitialized
if the loop finished in its first iteration because of no channels to
be processed.

Correct the size of the channel_setup_cfg array, as it should contain
entries for all available channels (AD4130_MAX_CHANNELS), not for the
available configuration slots (AD4130_MAX_SETUPS).
Move also checking of the channel index to the very beginning of
adc_ad4130_channel_setup(), to avoid potential writes to .live_cfg
beyond the channel_setup_cfg array.
