ASoC: msmcobalt: remove custom PM QoS for Low-latency playback
For msmcobalt, it was found that, for low-latency audio playback, audio driver requests for a PM QoS with 10% of the period size. This value is too small for CPU to come back up from L2 PC, and hence CPU never enters into L2 PC, which increased power consumption. ALSA core framework already has a way to vote on behalf of client driver, with a latency value of 75% of period size. To enable CPU to enter L2 PC, fall back to use ALSA core provided PM QoS of 75% for low-latency audio playback instead of the custom PM QoS request.
