Resuming from a suspend/resume cycle, the ACTIVE bit was not set even if a stream had actually been processing. Setting this bit at entering SND_SOC_BIAS_ON level will ensure this.

This will set the bit even for analogue bypass paths which don't need it. I'd suggest making the active bit a supply widget supplying the DAC and ADC rather than something open coded, that should do the right thing I think.
