Subject: [PATCH 0/2] Fix headset mic on Acer Nitro 5

The headphone jack on the Acer Nitro 5 AN515-58 laptop with the 
realtek ALC287 codec does not pick up any input from the mic,
this has been documented in multiple forum posts[1][2].

This patch adds a new fixup model and a PCI quirk which adds the
required pin configs and verbs necessary for microphone input.

The pin config and verbs were obtained by reverse engineering
the windows driver using RtHD dump.
