asoc: codec: Playback Amp power up/down time optimization.
In-order reduce the power down and hence to improve
audio-server restart time following time optimization is done.
1. Add common delay after both Amp is powered down.
a. Use 16ms instead of 20ms
2. Remove extra delay added in tas256x_set_power_shutdown()
3. Use usleep_range() instead of msleep for less than 20ms in
power up/down related functions.
