Subject: [PATCH] PCI/PM: Extend Elo i2 quirk to all systems using Continental Z2 board

The quirk for Elo i2 introduced in commit 92597f97a40b ("PCI/PM: Avoid
putting Elo i2 PCIe Ports in D3cold") is also needed by EloPOS E2/S2/H2
which uses the same Continental Z2 board.

Change the quirk to match the board instead of system.
