ASoC: msm8x10-wcd: Reduce pop noise when earpiece is switched fast 



In some scenarios, earpiece will be switched on just after turned off,
which will cause the audible pop noise in earpiece.
And if customer increases the EAR PA gain, this noise can be much louder.
So enable the SND_SOC_DAPM_POST_PMD event for EAR PA kcontrol
to stablize the PA.
