media: stm32: dcmi: perform all dma handling within irq_thread

Move all the type of frame handling within the dcmi_irq_thread
handler and do not rely on dma_callback as previously.

This simplifies the code by having only a single path for both
compressed and uncompressed data while also making the system
more reactive since irq_handler have more chances to be called
faster than the dma completion callback.  Indeed, in case of the
dma completion callback, this run as a tasklet created by the
dma framework upon getting an interrupt from the dma and run
at a lower priority level than other irq handlers.
