ASoC: msm8994: Make sure MAD widgets are not disabled during suspend

During suspend, the asoc framework will try to power down the widgets if
any are active. For MAD widgets this is problematic as these widgets are
needed even in suspend state. It also causes problem to bus used for
codec control interface by holding the bus from suspending. Since, these
widgets are required in suspend state, mark them to ignore suspend.
