[PATCH RESEND 3/5] mfd: arizona: Add register bits for general purpose switch

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

The switch is typically used in conjunction with the MICDET clamp in
order to suppress pops and clicks associated with jack insertion.
