Array or...

Scalar?

What's the difference with this and bit 3 of everest,jack-pol?

We already have numerous vendor properties for jack detect. Can we come 
up with something common?

The problem with 'inverted' is it assumes you know the non-inverted 
state. Better to just state high or low.

This property is in compatible with the property in es8316.c and sof_essx8336.c.
(which is not documented in es8316.yaml, another problem)
There is a quirk in sof_essx8336.c so that when the user find they're having a 
wrong jack insert configuration, they can set the quirk to invert it.
