ALSA: hda/tegra: Enable Jack poll for tegra

Enable HDA Jack polling for the tegra platforms as Jack detection
logic doesn't work when the HDACODEC in runtime suspended state as
unsol event won't be triggered during D3 state. This will help the
userspace audio setting controls to correctly show available audio
devices in gui.
