ASoC: nau8821: Add DMI quirk mechanism for active-high jack-detect

Browse Source 
Add a quirk mechanism to allow specifying that active-high jack-detection
should be used on platforms where this info is not available in devicetree.

And add an entry for the Positivo CW14Q01P-V2 to the DMI table, so that
jack-detection will work properly on this laptop.
