Before adding new Semtech sensors, move common logic to all Semtech SAR
sensor in its own file:
- interface with IIO subsystem,
- interrupt management,
- channel access conrol,
- event processing.
The change adds a bidirectional interface between sx93xx and sx_common.
The change is quite mechanical, as the impacted functions are moved
and renamed.
