ALSA: hda/realtek - Enable the ALC292 dock fixup on the Thinkpad T460s

[ Upstream commit c636b95ec5980345674ad7960a3c67135a84b687 ]

The Lenovo Thinkpad T460s requires the alc_fixup_tpt440_dock as well in
order to get working sound output on the docking stations headphone jack.

Patch tested on a Thinkpad T460s (20F9CT01WW) using a ThinkPad Ultradock
on kernel 4.4.6.
