This makes the code a bit shorter and cleaner. Also remove the extra write that sets the WM8711_ACTIVE register to 0x00 in the suspend handler since this write is already done when transitioning to SND_SOC_BIAS_OFF. Since the ASoC core now takes care of setting the bias level to SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually anymore either. The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe() can also be removed as the core will automatically do this after the CODEC has been probed.
