!2489 Some optimizations for PTT driver

Merge Pull Request from: @lujunhuaHW 
 
This series contains several updates for PTT driver:

Disable interrupt when trace stops, reverse to what we do in trace start
Always handle the interrupt in hardirq context
Optimize the AUX buffer handling to make consumer have more time to process
the data
Since we're a uncore PMU so block any task attach operation
