Subject: [PATCH v2] mxcmmc: update the regulator support code to the latest
 API

This fix also the build problem introduced by my previous patch
due to not handled API changes introduced by commit:
 99fc513 (mmc: Move regulator handling closer to core)

This patch apply to the current mmc-next branch
