Subject: [PATCH] media: stm32: dcmipp: bytecap: clear all interrupts upon
 stream stop

Ensure that there are no pending interrupts after we have stopped the
pipeline. Indeed, it could happen that new interrupt has been generated
during the stop_streaming processing hence clear them in order to avoid
getting a new interrupt right from the start of a next start_streaming.
