4.19-stable review patch. If anyone has any objections, please let me know.

From: Hui Wang <hui.wang@canonical.com>
commit d06fb562bff5d14defdacbd92449bacbaedd5cdf upstream.
The front MIC on the Lenovo M715 can't record sound, after applying the ALC294_FIXUP_LENOVO_MIC_LOCATION, the problem is fixed. So add the pin configuration of this machine to the pin quirk table.
