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.

The DPSRAM ports can run at different clocks, this is the default
configuration, follow the advice in the datasheet and wait 3 nop
instructions before setting the AVAILABLE bit.
It can be observed that when the controller is continuously sending data
to the host, it rarely has a 0-byte transaction instead of a short
packet. The reason for this is not easy to find, it also seems to depend
on the runtime of individual components. This may fix the problem, but
there is no sure proof that this is the solution.

When building `native_sim` with CPP & POSIX enabled, the
POSIX's `unistd.h` header causes a compilation error as
`sys/_timespec.h` doesn't exist in host gcc lib.
Remove the 'zephyr/posix' prefix, and rely on
`CMakeLists.txt`s to do the routing accordingly:
- zephyr/lib/CMakeLists.txt:L11
- zephyr/lib/posix/options/CMakeLists.txt:L8

The sample will print a ping-pong message indefinitely on both,

device testing mode, only one terminal is evaluated (application), so
the regex just needs to account for the application core output, not
remote.
