ALSA: hda: Poll jack events for LS7A HD-Audio

Browse Source 
LS7A HD-Audio disable interrupts and use polling mode due to hardware
drawbacks. As a result, unsolicited jack events are also unusable. If
we want to support headphone hotplug, we need to also poll jack events.

Here we use 1500ms as the poll interval if no module parameter specify
it.
