ASoC: cs42l43: Add shared IRQ flag for shutters
The microphone and speaker shutters on cs42l43 can be configured to
trigger from the same GPIO, in this case the current code returns an
error as we attempt to request two IRQ handlers for the same IRQ. Fix
this by always requesting the shutter IRQs with the IRQF_SHARED flag.
