Subject: [PATCH v3 2/3] HID: quirks: Fix keyboard + touchpad on Lenovo Miix 630 for DT

Following up on commit 2bafa1e96254 ("HID: quirks: Fix keyboard + touchpad
on Lenovo Miix 630"), the devicetree (DT) identifier for the combo keyboard
+ touchpad device is "elan,combo400-i2c", which differs from the ACPI ID,
thus if we want the quirk to work properly when booting via DT instead of
ACPI, we need to key off the DT id as well.
