First of all,the address of pdev->dev is assigned to card->dev in
create_card,then the function platform_set_drvdata copies the value
the variable card to pdev->dev.driver_data, but when calling
snd_soc_register_card,the function dev_set_drvdata(card->dev, card)
will also do the same copy operation,so i think that the former copy

When playing a sound for the first time, a short delay, where the audio
file is not played, can be noticed.
On a second play (right after), the sound is played correctly.
If we wait a short time (~5 sec which corresponds to the aplay
timeout), the delay is back.

This patch fixes it by using an event on headphone amplifier.
It allows to keep the amplifier enable while playing a sound.
A delay of 700ms allows to wait that the amplifier is powered-up
