Subject: PCI/PM: Avoid putting EloPOS E2/S2/H2 PCIe Ports in D3cold

From: Ondrej Zary <linux@xxxxxxx>

commit 9e30fd26f43b89cb6b4e850a86caa2e50dedb454 upstream.

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.
