ASoC: wm8804: Remove unnecessary suspend/resume bias level changes
The ASoC core will only call the suspend/resume callbacks when the device's DAPM context is idle. Since this driver sets idle_bias_off to true this means that the device is already in SND_SOC_BIAS_OFF when the suspend callback is called, so there is no need to manually set this state again. There is also no need to go to SND_SOC_BIAS_STANDBY in the resume callback since the core will go right back to SND_SOC_BIAS_OFF.
