[ Upstream commit b38d478dad79e61e8a65931021bdfd7a71741212 ]

The Lenovo ThinkPad X1 Fold 16 Gen 1 has physical volume up/down
buttons that are handled through the intel-hid 5-button array
interface. The firmware does not advertise 5-button array support via
HEBC, so the driver relies on a DMI allowlist to enable it.

Add the ThinkPad X1 Fold 16 Gen 1 to the button_array_table so the
volume buttons work out of the box.
