mfd: wcd9xxx: Disable codec interrupt if HW doesn't respond
The codec interrupt line is level type which can be cleared by writing
codec register through connected bus.
If codec registers are not accessable due to various reasons including
hardware issues, there is chance driver never be able to clear irq that
results in irq flood.
Prevent this irq flood by disabling irq if codec doesn't respond.
