[PATCH 5/6] mfd: arizona: Add support for new micbias regulators

[Charles Keepax <ckeepax-yzvPICuk2AATkU/dhu1WVueM+bqZidxxQQ4Iyu8u01E@public.gmane.org>]

Add mfd_cell's for each of the new micbias regulators,  provide the
appropriate supply mapping for these, and remove the old code that
configured the micbiases now that the regulator driver does so.
