mfd: wcd9xxx: send down notification to devices before cleaning-up IRQs



IRQ clean up should be done only after codec devices have been
notified with device down. Without this, there are chances of
race-condition where some of the resources like locks used for
safe handling of the IRQs would be used after those are freed.
