mfd: wcd9xxx: Fix interrupt request flooding
The wcd9320 and wcd9306 codec have additional interrupt bits which are not
currently masked. Therefore it's possible those interrupts assert and
never be cleared by driver. Mask additional interrupt mask bits in order
to prevent irq flooding.
Additionally enhance irq handler to clear unhandled nested irq so even
buggy driver cannot make irq flooding.
