i2c: qcom-geni: use dedicated completions for abort and reset events

Browse source

The driver uses a common completion event for transfer, abort and DMA
reset operations.  This allows unrelated completion events to
prematurely wake abort and reset waiters, leading to incorrect
synchronization.

Introduce dedicated completions for abort, TX reset, and RX reset
operations, and signal them only from their respective interrupt
events.  This removes the dependency on shared completion state and
eliminates the abort_done flag-based synchronization.
