Subject: [PATCH v6 5/5] mfd: arizona: Update DT doc for new mic detection bindings

As this patch is still outstanding from the last series I
just updated the patch from the last series to include the
additions from this series.

This patch can obviously be applied seperately from the
rest of the series as there are no dependencies but I have
included it so everyone can see the series together.

Thanks,
Charles
