mfd: Use completion interrupt for WM835x AUXADC
Use the completion interrupt generated by the device rather than polling for conversions to complete. As a backup we still check the state of the AUXADC if we don't get a completion, mostly for systems that don't have the WM8350 interrupt infrastructure hooked up.
