baytrail: use common code for iosf accessors

The same sequence is used regardless of the port
    being read or written. Therefore, use the same
    implementation for reading or writing to a port.

BUG=None
    BRANCH=None
    TEST=Built and booted through depthcharge. Dev and recovery
         screens still work. Nothing bizarre in console output.
