[ Upstream commit 3ef9d5073b552d56bd6daf2af1e89b7e8d4df183 ]

The microphone-jack state needs to be masked in a case of a 4-pin jack
when microphone and ground pins are shorted. Presence of nvidia,headset
tells that WM8903 CODEC driver should mask microphone's status if short
circuit is detected, i.e headphones are inserted.

This is a new feature not a bugfix.

I saw this patch more as a hardware quirk.
