ASoC: wm8962: Don't report a microphone if it's shorted to ground on plug

Browse source

[ Upstream commit e590752119 ]

This usually means that a TRS plug with no microphone pin has been plugged
into a TRRS socket. Cases where a user is plugging in a microphone while
pressing a button will be handled via incoming interrupt after the user
releases the button, so the microphone will still be detected once it
becomes usable.
