ASoC: wcd9310: Add parameter to set delay after lineout PA enable

The speaker PA in moto_msm8960 2012 line needs longer sleep time
after it gets enabled, to prevent audible pop at the beginning of
playback. The necessary 32000us delay will be set from userspace
init scripts on devices that need it.
