ASoC: wcd_cpe_core: Fix interrupt requests during SSR

When the bus to the codec goes down, the codec interrupt handlers need
to be freed and re-registered to make sure the interrupts are routed to
correct handlers. This fixes the issue of CPE becoming unresponsive once
the underlying bus goes down and comes back up again.
