HP output driver has two parameters that can be configured to reduce pop noise: power-on delay and ramp-up step time. Two new kcontrols have been added to set these parameters.
Also have to alter timeout in aic31xx_dapm_power_event() because default timeout does fire when higher supported power-on delay are configured.
