ALSA: hda/realtek - ALC292 dock fix for Thinkpad L450

[ Upstream commit 09ea997677cd44ebe7f42573119aaf46b775c683 ]

The Lenovo ThinkPad L450 requires the ALC292_FIXUP_TPT440_DOCK fix in
order to get sound output on the docking stations audio port.

This patch was tested using a ThinkPad L450 (20DSS00B00) using kernel
4.0.3 and a ThinkPad Pro Dock.
