Update board overlays for boards with LPADC IP present on their SOCs, to
use new LPADC API for channel numbering.
For the RT595 and LPCxpresso55S69 EVKs, additional channels are enabled

Simplify sample by relying exclusively on channel data from Devicetree.
This change makes sample simpler and more portable at the same time.
Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>
It is now possible to configure ADC channels in Devicetree. This makes
code more portable, since there is no need to hardcode hardware specific
bits in the C sources.
This patch adds channel/s configuration for all support sample overlays.
Hardcoded values have been used:
- Resolution: 12-bit
- Gain: 1
- Reference: internal
- Acquisition time: default
Some nRF channels have been adjusted to include resolution as well.

This is a follow-up to commit f5ffd05e6b.
Since twister removes leading spaces from received lines before
further processing, the regular expression for checking the output
produced by the sample cannot contain such space. Also negative
values read from ADC channels need to be allowed.
For consistency, remove the leading space also in the actual string
printed by the sample.

The overlay for the nRF52840 DK board uses ADC controller child nodes
for specifying channel configurations and it shows how to configure
a channel in differential input mode, so it can serve as an example
of how to use these new possibilities. The overlay for the nRF51 DK
board shows how to use a specific ADC resolution (the default 12 bit
setting is not supported by nRF51 SoCs).

Allow specifying configuration of channels through child nodes of ADC
controllers. This way analog inputs can be specified for channels in
SoCs that require this and it is also possible, for example, to use
different gain or reference selections for particular channels.
This commit also removes a few former limitations of the sample: now
it is possible to use more than 2 channels and each channel can use
a different ADC controller. Also the ADC resolution to be used can be
specified through devicetree.
