ALSA: hda/realtek - Fix pop noise on Lenovo P50 & co
Some Lenovo laptops, e.g. Lenovo P50, showed the pop noise at resume or runtime resume. It turned out to be reduced by applying alc_no_shutup() just like TPT440 quirk does. Since there are many Lenovo models showing the same behavior, put this workaround in ALC269_FIXUP_THINKPAD_ACPI entry so that it's applied commonly to all such Lenovo machines.
