scsi: ufs: Export regulator functions

Browse Source 
Export below regulator functions to allow vendors to
customize regulator configuration in their own platforms.

int ufshcd_populate_vreg(struct device *dev, const char *name,
                         struct ufs_vreg **out_vreg);
int ufshcd_get_vreg(struct device *dev, struct ufs_vreg *vreg);
