  Add STM32 ADC2 internal channels VREFINT and VDDCORE to STM32MP15x SoCs.

Add support of vrefint channel by adding access to vrefint calibration
data in OTP.

The internal channels are defined in STM32MP15 SoC DT according to
generic channel bindings. The STM32 driver does not support a mixed use
of legacy and generic channels. When generic channels are defined,
legacy channel are ignored. This involves that the board device trees
using legacy bindings have to be changed to generic bindings.

Adopt generic iio bindings on STM32 boards implementing the ADC.

Changes in v2:
- Add patch from https://lore.kernel.org/linux-arm-kernel/20230518020547.487670-1-marex@denx.de/T/
- Change node name from vrefin_cal to vrefin-cal
