ASoC: nau8821: Generalize helper to clear IRQ status

Instead of adding yet another utility function for dealing with the
interrupt clearing register, generalize nau8821_int_status_clear_all()
by renaming it to nau8821_irq_status_clear(), whilst introducing a
second parameter to allow restricting the operation scope to a single
interrupt instead of the whole range of active IRQs.

While at it, also fix a spelling typo in the comment block.

Note this is mainly a prerequisite for subsequent patches aiming to
address some deficiencies in the implementation of the interrupt
handler.  Thus the presence of the Fixes tag below is intentional, to
facilitate backporting.
