Devreese Jorik 8fd6bf1a49 mixer: fix cache coherency issue in multi-application scenario
Remove conditional hardware writes in set_volume_ops and set_switch_ops
to ensure hardware state is always updated. This fixes an issue where setting controls
to the same value repeatedly does nothing, even if the hardware state has changed
due to actions from other applications.
