[PATCH 0/7] add internal channels support

[Olivier Moysan]

This patchset adds support of ADC2 internal channels VDDCORE, VREFINT and VBAT
on STM32MP15x SoCs. The generic IIO channel bindings is also introduced here
to provide this feature. The legacy channel binding is kept for backward compatibility.
