Commit 47187a9ec9 made the `pinctrl` property
of STM32 ADCs optional, to allow usage of internal channels without wasting
GPIO pins. However, the driver was not adapted to support this new usecase.
(The real bug comes from commit 93956b2073,
that transitioned from a custom `stm32_dt_pinctrl_configure` function to
the standard `pinctrl_apply_state`, without accounting for the fact that
the former returns 0 when pinctrl is empty, but the latter returns -ENOENT)
Modify the driver to work even if no `pinctrl` is present on the ADC node.

The NRF SAADC produces negative values in single ended mode if the
positive input is below 0V (ground). This behavior does not match
the ADC device driver API, which states that in single ended mode,
the readings must be positive [0 .. 2^resolution - 1].
This commit extends the adc_nrfx_saadc device driver to track which
channels in a sequence are configured to be single ended, to then
corrects negative readings for these channels to 0.
This patch only works if the ADC resolution is lower than the sample
bit size. This is the case for 8, 10, 12 and 14 bit resolutions for
the nRF 52, 53 and 91 series which store readings in a int16_t.
The nRF 54H and 54L series store 8-bit resolution readings in a 8-bit
sample size. A check has been added to start_read() to prevent single
ended mode readings if the resolution is 8-bit for these platforms.

Burst mode enabled on an unused channel causes a freeze during a
conversion consisting of several channels (not including the one with
burst mode enabled).
Discovered on nRF52832 (nRF52-DK) using the following approach:
channels 0-3 are used for application purposes as a sequence
channel 4 is used for battery measurements with oversampling
After few successful conversions the sequence (channels 0-3) freezes the
thread while waiting for semaphore to end the conversion.

Namespaced the generated headers with `zephyr` to prevent
potential conflict with other headers.
Introduce a temporary Kconfig `LEGACY_GENERATED_INCLUDE_PATH`
that is enabled by default. This allows the developers to
continue the use of the old include paths for the time being
until it is deprecated and eventually removed. The Kconfig will
generate a build-time warning message, similar to the
`CONFIG_TIMER_RANDOM_GENERATOR`.
Updated the includes path of in-tree sources accordingly.
