ASoC: Disable WM8994/58 microphone detection over suspend
It will be non-functional with the basises and clocks off anyway, if the system needs microphone detection enabled over suspend then it should be causing the CODEC to ignore suspend using the APIs for that to prevent the biases being disabled.
