The ntc_temp2 lookup table was declared as 'char', which can be
unsigned on some platforms, causing negative temperature values
(-30°C to -1°C) to be incorrectly interpreted.
Changed to int8_t to ensure proper signed integer handling of
negative temperatures.

As all NRF52 boards now have OTA support, let's remove the subclass
and integrate it into the base class.

The schematic shows the LC circuit for the internal DC/DC regulator
to be available. Enable it to save power.

The Ikoka boards are based on the Xioa NRF52840 module which is known
to have the LC circuit for the internal DC/DC regulator to be
available. Enable it to save power.

The RAK4631/RAK4630 module are able to use the DC/DC converter. Enable
it to reduce power consumption.

The startOTAUpdate() is the same for all NRF52 boards. Use a common
implementation for all boards that currently have a specific
implementation.
The following boards currently have an empty startOTAUpdate() for
whatever reasons and therefore are not inheriting NRF52BoardOTA to
keep the same state: Nano G2 Ultra, Seeed SenseCAP T1000-E,
Wio WM1110.

Some NRF52 boards are able to use the internal power-efficient DC/DC
regulator. Add a new class that can be inherited by board classes to
enable this feature and reduce the power consumption.

Use a common begin() method that can be called from derived classes
to contain the shared initialization code.
