Subject: [PATCH 2/2] extcon: arizona: Don't require micbias to be shifted in pdata

Every other pdata field is specified unshifted the patch handles
shifting for the MICBIAS from the microphone detection polarity
configurations in the extcon driver rather than demanding it in
pdata to match other fields.
